I make a lot of jackets and there are a number of patterns for them.It is the only time I wash my fabric nad I use flanalette for the batting, washed 2-3 times in HOT water to make sure the shrinkage is out of it . If not sure of what size make a sample from a cheap muslin or a old sheet. They are great to wear and can be to embellised to your hearts content with beads lace ribbon and charms Good Luck and have fun
