Let me get this straight. If my border is 10" ( I like that size border for the drop) then I would need to make total border strip 10" +11+11 (for each side) + the length of the side border is to be sewn on. EG- side is 70" so 10" border strip needs to be 70+10+11+11=102" This lengeth means that I would have to cut an extra 30" strip x width for each side.(4 extra strips) of each strip width. Basically it would be 1 extra WOF strip for each side. So if border peice is 6" then I would need 4 -6 1/2 "WOF cuts =26" extra. That is almost an extra yard of fabric. Seems like a lot. Maybe I will have to rethink this!
