Thank for the replies and suggestions
. I think I will just serge the edges of the yardage and go ahead and do the prewash..as was mentioned, I know flannel does shrink and I don't want the quilt going wonky and most of the pieces are dark colors too so bleeding might happen. I just hate having to iron all that yardage before I can start the fun part! Also..I bought a lot of yardage because I knew it would shrink and wanted to make sure I had enough and to allow for nice seams and last but not least, my DH is a big and tall guy, so he needs a HUGE quilt...lol! I am still a very new quilter so figuring yardage isn't my strong point yet. This rag quilt will only be my second quilt ever as well as my first raggie. I did consider not using batting in it but my DH freezes here at home because I keep the house very cool in the summer and about 60-65 degrees in the winter. I don't want to have to mess with going to a laundromat to wash the quilt..mainly because the nearest one to me that would have the huge machines is about 40 miles away..so that is why I thought maybe the big sheet sewn in half to wash the quilt in might work..so all the strings don't clog up my machine or plumbing.
