These little zippered wool bags continue to keep my fingers busy in the evenings. Rather than using National Nonwoven's Woolfelt, I've dug into a stash of 100% wool. The extra sturdiness of this much thicker wool has its benefits, but obtaining sharp corners is impossible. Although I've washed the fabric several times in an attempt to felt it, the quality of the fiber is fine so true felting isn't possible. So, what does that mean?? Answer: the edges have to be surged or finished in some manner due to the fraying which creates bulkier seams.
I'll be experimenting some more....in the mean time, the heavier fabric is still a good choice especially for 'working' pouches as they are bound to hold up better.
