  I am starting the urlLink French Market Bag from Knitty . It has a rounded bottom that you do on 5 double pointed needles...way too advanced for me. I opted for the flat rectangles bottom. I got a beautiful Galloway wool in moss green with a small colored fleck. My only concern is it is 93% wool and 7% polyester!!!! Will it still felt!!?? I know the simple answer here is swatch it and see, but I am a lazy knitter and that just sounds like too much work.
