I love learning new skills, and we have so many amazing resources at CU. On my list for a while have been the industrial sewing machines at the ITLL. I designed and built a pack that allows me to avoid bringing a backpack when commuting or out for long rides. I followed this tutorial pretty closely, but designed my template in onshape to allow me to keep a water bottle on the frame, and then laser-cut the fabric pieces. I'm pretty happy with how it turned out, and I got a fair bit of practice sewing along the way.
