I was thinking more about the weaving as a way to sewing better, and I think it really does have some merit. The more comfortable you are with a material, the more you can focus on what you need to focus on, instead of being distracted by trying to figure out too many things at once. That's one of the reasons I focused on spinning with a drop spindle first for spinning, because I couldn't deal with the treadling at the same time. Knowing what your fabric will and won't do will help a lot. Also might help with things like making appropriate fabric choices -- something I don't always get quite right still, at least when it comes to lining fabrics (they should match in behavior to the outer layer of fabric or else life gets really.... interesting....)

and thanks for the vote of confidence :)
