Many of you requested I make available a version of my <3 necklace, so here it is! Order one on Makers Market or Etsy now for $160.

This 1.5 inch tall Sterling silver pendant is handmade from 1mm thick sheet and tubing, depicting the internet-savvy sentiment <3, an ascii heart! Appropriate for showing your geeky ladyfriend how much you care. The < and 3 dangle freely, dancing near each other with the wearer’s motions. Available with a 19 inch long 3mm leather cord or Sterling silver chain. Finished with a Sterling clasp and packaged in a black jewelry gift box.

If you want to make your own (to wear or give, not sell, please), here’s the template I used to pierce the shapes:

I’m working on some felt electronics, this time pushbuttons in addition to knobs. Moxie taught me how to needle felt, which makes it easier to form a dense defined shape than with wet felting. I first make little marshmallow-shaped cylinders, then bore a hole and insert the button or knob. A few more pics are at my Flickr.

This weekend I’m in Seattle at Urban Craft Uprising’s first ever summer show, and it’s a blast. I did a soft circuit demo, and doing another one Sunday at 1:30pm. I’m selling LED sewing kits, so if you’re looking for the tutorial, click on through. Pictured above is the incommutable Moxie herself.

I’ve been making plush squids again, and this time I published a free (creative commons by-sa license) pattern to go along with them, so you can make your own. The one pictured above is named “Mr. Caissy from Accounting.” See more plush squids in my Flickr set.

I recently won a raffle for a Makerbot Cupcake CNC machine, which is a DIY 3D printer. The raffle was held by AS220, an awesome hacker/etc lab in Providence. Thanks a million, guys, it works great! You can find the file for the little mushroom that I printed (John Park modeled it) in the Thingiverse.
