If you don’t want to wait until the New Year to start a new hobby, Erica Stratton will be teaching more free classes this month at the Martin Luther King Jr. Memorial Library. Here’s the full schedule:

December 3rd: How to Make a GIF

Have you been wishing you could make awesome animated GIFs just like they do on Buzzfeed? Well, wonder no more! This hour-long class will show you how to create your very own GIFs using Photoshop CS6 and Quicktime. RSVP here.

December 6th: Introduction to 3D Printing

During this hour-long class we’ll explain everything you need to know about how different kinds of 3D printers work, give demos of 3D design programs that you can use to create your own items, and finally show you how you can have your design printed in plastic by MLK’s 3D Print Crew! RSVP here.

December 17th: Designing Jewelry for 3D Printing

If you missed it last month, we’re teaching this class again! We’ll show you how to create a simple bracelet digitally using TinkerCAD, then walk you through the process for getting it printed in recyclable plastic by MLK’s 3D Print Crew. RSVP here.



Learn to design jewelry for a 3D printer this Wednesday!


Tired of turkey prep and want to learn something new? Erica Stratton is teaching free tech classes at the Martin Luther King Jr. Memorial Library this month. She would like to invite all Spanning Tree members to participate in her next class,  “3D Printing: Jewelry Design”.

Erica will  show you how to create a simple bracelet digitally using TinkerCAD, then walk you through the process for getting it printed in recyclable plastic by MLK’s 3D Print Crew. The class is this Wednesday (November 26th) so be sure to RSVP now!

Come and learn to use Twine with us!

Twine is a program that allows you to create interactive stories without having to know code (check out Worm Industrial Revolution or Even Cowgirls Bleed). The stories can then be posted almost anywhere on the web.

HacDC will once again be hosting us for this four-hour class. You won’t need to know code to take this class, but it’s recommended that you bring a laptop so that you can follow along. Be sure to RSVP here!



Our first-ever class was pretty great


Yarn, glorious yarn!

Our students turned out to be a very diverse group. We got people of all ages and backgrounds, united in the quest to learn how to knit. Once they figured out casting, we settled in to talk about the difference between English and Continental styles, the proper way to hold a needle (“Like you’re going to stab someone!”) and how knitting patterns are like programming languages.

“It doesn’t matter, yarn happened.”

People have already begun asking if we’re going to do a basic sewing class. We just might!


Learn to Knit and Crochet with Us!

Spanning Tree is proud to present our first class! Learn to wield a crochet hook or knitting needle with us at HacDC on July 11th.

During this two-hour class, you will learn basic knit and crochet stitches that you’ll use to create a washcloth. Needles and yarn will be provided. Space is limited, so be sure to register by emailing!

Never been to HacDC before? You can get here by Metro, by bus, or even by bicycle. Looking forward to seeing you there!


DC Mini Maker Faire & What’s Next

“Make” buttons from the DC Mini Maker Faire

Spanning Tree had a table at the DC Mini Maker Faire this past Sunday! We really enjoyed talking to people, as well as showing off Becca’s eggbot and my 3D printed jewelry. The Maker Faire also wrote an extremely nice blog post about us, which brought many new faces to our table and visitors to their site!

Several people at the Faire asked what’s next for us as a group. Right now, Spanning Tree’s biggest goal is finding a space– preferably in DC–where we can set up our robots and sewing machines and start having classes. Until we find that space, we’re discussing making guest appearances at other hackerspaces to teach.  Our first class will probably be about knitting, so watch this space for updates!
