Feb 3, 2022, 12:20PM to 2:10PM

Welcome! The main objectives for today are to introduce heat sealing tools and a tour of IDeATe space.


  1. Next week we will jump into using the sewing machines. On Tuesday, Feb. 8 (next week), those who have a lot of sewing machine experience or have taken any of these courses (Soft Fabrication, Intro to Textile Media, Inflatables, Garments) do NOT need to attend class.
  2. We will take measurements for the vests on Thursday, Feb. 10 (next week). Please wear a close-fitting shirt for that portion of class.
  3. Ozgun Kilic Afsar, of OmniFiber, is a visiting speaker (via zoom) next week Tues. Feb. 8 in the Morphing Matter lab. Check your email for the zoom link which Olivia sent to you all. Optional to go – but recommended!
