I have used them as regular fabric also. Just sew them into your connecting blocks as you normally would. I made these wall hangings using photo fabric sheets.

[ATTACH=CONFIG]586429[/ATTACH] [ATTACH=CONFIG]586430[/ATTACH]I made these for my husband's family. I used family photos....of the couple and each set of their parents and their children. They are Irish, so used Irish themed fabric for the "non-photo" blocks. I made these just as I was starting to quilt in 2011. So they are quite simple... I would make better improvements today with the non photo blocks using different block patterns.
