Im wanting to make a memory quilt out of my FIL flannel shirts however they are stretching alot when I press.. I have never used stabilizer nor interfacing and am at a loss for what I need to look for. So I need help.. Can anyone suggest the best stabilizer or interfacing they have ever used? Speaking of which, Can I use either stabilizer OR Interfacing? is one better than the other.. Should I not use one or the other.. .. HELP !!!!!
