i too am a STRING BLOCK LOVER!!! instead of muslin, I use the ''why did I ever buy that fabric'' fabric for the foundation layer. The only thing is that you have to watch those very light fabrics letting the foundation fabric show through but if I'm a bit concerned, I just grab 2 light strings and layer them....no problem!! String blocks do have a way of multipuling overnight but the quilts are just so cool!!
