Burning crafting question

[colliemommie]

I have a wool sweater I want to make into a laptop bag. So, do I cut it apart, use yarn to sew the pieces together, and then felt it, or do I felt first, then sew?

The downside of felting last is that there's no way to 100% guarantee the finished size. It might not be a laptop bag. But stitching with wool yarn and then felting means it will meld together and be pretty darn untearable.

The downside of felting first is having to sew felt.
