Christmas Gift Making


I wonder if I was a Santa Elf in one of my previous lives...

It's nearly time for some keen folks' mid year Christmas, so probably about time for the 2013 Christmas gift making round-up.  For someone who is a fist shaking festive grinch, I sure do put a lot of effort into designing and making gifts for family.  It the only way I can think of to turn something I loathe, which is shopping for gifts into an enjoyable experience, which is creating something in my personal sweatshop - *ahem* - workroom.

Last festive gifting involved printing some photo books, making some food and the usual sewing and toy making.  There seems to be an emerging theme of DIY toys, clothes, food and photography.

I should be about the last person in the western world to want to do this, but I even sewed a holiday outfit for my daughter.  Red and white happen to be her colours, and my weakness for elephants compelled me to buy elephant print cotton

Jewellery Trees: Rimu, Stainless Steel, Plywood, Jarrah

It's official.  We have now supplied all of our closest women relatives with jewellery trees of different designs.

The latest, for my youngest sister-in-law, is a free-standing laser cut Rimu Veneer "fruit" tree.  Mmmm fruit. I'm thinking oranges.  "Veneer" generally denotes an MDF core, which is a material I tend to despise.  However, it does have its uses, and is fantastic for laser cutting, especially the veneers.  Check out examples of how veneer MDF can be used at Ponoko.

The other sister-in-law received an extra-tall tree cut from 6mm Eurolite.  The design is by Robyn Ward, and I added the engraved pattern to all the faces.  The original tree design is covered by the GNU General Public License, but I'm certain that an application of a surface treatment is not considered as a change to the design, which is something that is excluded from this license.

Then there was the wall mounted tree cut from 3mm alluminium and powder coated white.  Styley as hell.  It doubled as a first prototype for a product, so I cannot yet post pictures of it.  Maybe one day.

Lastly, there was a very involved stainless steel, acrylic on a jarrah base - a Christmas present from a couple of years ago, which I'm yet to document in a blog post of its own.  Maybe one day.

All the four trees are elegantly carrying out their duties, dutifully bearing a heavy load of jewellery.

Mirror Mouse Buttons For a Cardigan

I like making custom buttons.  It's another tool in the turd polishing repertoire when it comes to garment enhancement.  
 

Although I'd like to think that the clothing I make doesn't have to rely on fancy buttons to look agreeable, the buttons can really complement the character of a garment.

These mice were cut from 3mm mirror acrylic and engraved on the reverse side.  I made the woollen cardigan from a friend's worn out sweater, and there's a tutorial for it coming soon.

Various Chromatophobic shirt and cardigan buttons are available from my shop.

Cardigan with Laser Cut Piggy Buttons

This little piggy went to a party, this little piggy waddled to a bbq, and these little piggies jumped on a merino cardigan.

 

The piggy buttons are available from my Storenvy shop.

Wool Felt Vases That Pack Flat

Floppy felt fail?  No way.  This baby is so stiff, it can take your eye out.
I used to shudder at mention of felt.  It conjured up images of hordes of screaming children running around with safety scissors during some sort of a ghastly craft lesson and making a horrible multi-colour mess.  Ughh colour.  I've never really been a fan of craft felt, but I understand that it has its uses.  Not unlike velcro.  Ughh velcro.

However, I absolutely love the 100% merino wool felt in the Ponoko catalogue.  I use it for the Chromatophobic coasters.

In its natural state the felt is quite soft, but it's easy to stiffen it with a 50/50 mixture of water and PVA glue.   The cut pieces are impregnated with the magic potion by dipping them into the milky bath and then drying them thoroughly.  It looks like you're making pretend french toast...  Once dry the pieces completely stiff, and the shapes can be assembled into 3D forms.

In this instance the 3D forms are vases.  In the centre of the vase is a glass test tube for the water and the plants you stole from your neighbours' garden.

Baby Boots Pattern

This little piggy went to the market...
Recently I did something I probably hadn't done since high school.  I purchased a commercial sewing pattern.  I came across a photo of some outrageously adorable baby boots and was about start making a pattern, when I realised that I could simply buy one for only $4.  Even I can afford that.  I found the instructions somewhat clunky, but the making process was reasonably straight forward if fiddly.


One change I made to the original design was adding some padding into the sole.  I also made the sole outer from vinyl, so it's remotely suitable for trying to walk on. Still these boots aren't really designed for walking in, as they don't provide enough support.  My Chromatophobic Piggy buttons are purely decorative because the boots have a velcro closure.  I consider velcro to be one of my mortal enemies most of the time, but I have to admit it has its uses.
As adorable as [I think] these tiny boots are, they don't stay on too well, so I will be adding some elastic around the ankle to remedy this problem.

The rest of Zaika's outfit is also made by me.  It's all merino wool, and the cardigan buttons are laser cut from polypropylene.

'71 MGB Race Car Clock


The making of an analogue time piece.
A bit over a year ago we rather ambitiously went on a frenzied but rewarding mission making everyone's Christmas presents.  I managed to document some of the projects in a timely manner, but lost steam half way through, letting the process photos gather the digital equivalent of dust and cobwebs.  Perhaps, it's time to unearth another one of those undertakings.

One gift I didn’t have to think hard about for a clock for my other half.  Well, there was a lot of thinking involved, but that involved resolving the design details as opposed to coming up with the concept.  We have a garage/workshop, which is my husband’s greasy second home.  He didn’t have a clock and couldn’t get his phone out of his pocket with filthy hands to check the time, so there were frequent issues with punctuality, especially around dinner time.  I set out to resolve this persistent concern with something of design significance to this wonderful man: his 1971 MGB race car.

I had the design finalised by mid November and cut the first prototype.  I gleefully patted myself on the back for being so organised with the whole Christmas whatsitnow.  The plywood clock face had the design engraved into it, and then the design was cut separately out of card and inlaid into the wood recess.  It worked perfectly, so I sent the files to the fabricator to have the inlay components cut out of brass.  After not hearing back from them for a few weeks, I got slightly anxious and called them, only to be told that they couldn’t cut brass and that they had emailed me about the issue.  The email must have been eaten by the internets because I never received it.  I really wanted the vintage look of brass, but by then it was too late to find another fabricator, so I made the decision to use stainless steel instead.  At least that would match the chrome of the car.

I firmly decided to avoid a last minute mad making panic A La Design School, so I forcefully crossed my fingers in hope of getting my parts back on time.  I couldn’t work on any other components until the metal parts arrived, so when I was told ten days before the deadline that my files were unreadable (despite being especially converted for industrial CAD cutters), I developed a persistent twitch to accompany my morning sickness.  What followed was a series of phone conversations with the fabricator where I had to convince them that the design was to be cut exactly as specified – I’d already prototyped it, and it worked, and no extra bridges were needed.  Yes, yes Cut As Is, Please I Know What I'm Doing scenario.

Finally, on the 21st of December, at the end of the work day, I had the parts personally delivered by the lovely factory manager.  I gave him tasty jam to say "thank you".  
Thank You jam
I spent the next morning frantically and painstakingly grinding off the unavoidable bridges between the laser piercing points to get my parts out of the unyielding sheet.  I wished I had a Dremmel and not a gutless little rotary tool.  Anyone who’s worked with stainless steel is familiar with its pervasive attribute for eliciting coarse language.  After much swearing, sweating and bleeding I had all the metal bits separated and laid out.  Fortunately, the parts turned out about 95% accurate to the design, which meant only minor tweaking of the original drawing to get the engraving of the clock face identical to the unchangeable stainless components.

Next came the inlay prep work.  Firstly, when you laser cut wood, you can't just grab the cut part and expect it to be good enough for a product.  I see those examples in the market place all the time, and it bugs the hell out of me.   A laser beams is basically a very concentrated fire.  It burns.  Intensely.  People seem to be surprised by that.  The heat causes charring on the material surface, in the direction of the pull of the extraction.  Quite a bit of sanding is required to tidy up the laser cut parts.

After all that grind, it was time for some serious effort to inlay the springy, shiny steel parts into the engraving without making a mess.  Getting the intricate MG cut-out to stay flat was remarkably difficult and incredibly frustrating.

Next step is sealing the clock to make sure that the wood lasts well.  I  decided on a spray lacquer.  Unfortunately I couldn't get into a ventilated paint booth, so had to do the spraying outdoors, at the mercy of Wellington wind.
Deciding between a wax and a lacquer.  Wax and metal should have been quite obviously a dumb idea.

I was on the receiving end of some suspicious looks from people who must have mistaken me for a tagging delinquent.  Several lacquer coats later the clock face was ready for its pointy hands.  I bought a cheap clock mechanism and swapped its paper thin aluminium hands for my custom cut ones.  Two days before Christmas the clock was finally complete and ready to be packaged into an insanely beautiful box made from some cardboard scrap.
