Made a jacket in corduroy. The two pieces of cloth from which it was assembled looked identical before pre-washing then turned slightly different shades of beige and rose when laundered. Solved the issue by using one piece for the sleeves, the other for the body of the garment. Will draft a pattern for longer sleeves (although the 3/4 length is nice....hum). Making a covered button was a first and for some reason very happy-making.(Three-quarter length jacket with covered button, cotton, 2009)
