I do wool applique and go to thrift stores, mainly Salvation Army and purchase wool coats and blazers. I wash them in hot water and toss in the dryer before taking them apart. This felts them and they don't fray when cup up. Amazing how much wool you can get and can't beat the price. On New Years day my friends and I do a thrift store shop hop as all clothing is 1/2 off. Last year I picked up a woman's long white coat for $10. I have many blazers and mens sport coats cut up and ready for any ideas that pop into my head.
