if you do it with glue (she uses the water soluble) and ever wash it, won't the edges fray? the iron on bonding keeps that from happening. with the bonding, you would bond first and then cut. just about all your stray edges would be bonded.
i do like the glue for other purposes. but i'm afraid of it for this purpose.
i still love yours. are you doing the whole set? i'm saving mine up to do as a whole set. i don't like to start a project and find out i missed a block somewhere along the way.
