I would take the finsihed knitted bag ... before felting ... to the sink and "hand wash" the stained part with cold water and laundry soap ... if that doesn't completely work, I would go on to a shout or oxy clean product. Once you have the stain out, then felt.
PS ... I will be there !!!!!!!
wanted to have it done for Distaff Day because there's a chance I'm going to invade the women's event and i think i'm at about 11 inches finally.
