I'd like to make some cleaning patches for my .32 cal; came across a post that recommended Wal-Mart "Super Flannel" which I'd like to try. Is flannel material supposed to be washed to remove sizing as well before being cut/torn to size? (I pre-wash my ticking for shooting patch strips). Also, what size should I cut those cleaning patches? (I found a previous post that stated to cut patches to 7/8", but I think that was shooting patches, not cleaning patches.) Lastly, is there a formula that I can extrapolate the proper size for other calibers?
