I am hoping I get some sort of idea how much yardage I will need to make an Irish Chain smaller than a twin but a good sized throw. All the places I have looked I cant get any info for the size I want to make. I did purchase Quilt In Day Irish Chain book but the 'squares' are cut larger than I want to use. I would like to make this with 2 1/2 inch strips. Anyone have a pretty good guestimate ???
