I use them in everything. Unless you are doing a quilt with very few fabrics & colors, then fqs are great! I love quilts with lots of different fabrics & colors in them, so they work great for me. I am doing more applique now, & they are great for that too. Yes, there are fq patterns, but don't limit yourself to just them. Fqs also give you alot more variety to choose from in your stash, & they don't stay around forever, like a whole bolt would, or even yards of any one piece. They are great when you don't have alot of room either... So, try some & see, you might get hooked on them!...
