Caley-I would do as you "suggested" cutting the blocks apart, starch or Best Press, re-press and cut them again into uniform sizes, I'm assuming you have a rotary cutter and mat. If not, PM me, and I'll send you a cutter, but I don't have an extra mat. I'm also assuming you have a quilting ruler also. I'm also assuming the already cut pieces are cotton fabrics.
Until you're able to get a 1/4" foot, you can also make your own 1/4" mark with painter's tape, layer several layers of tape until it creates a ridge, and use that ridge as your guide.
