I am doing a guest book quilt instead of a normal guest book. I know how I want to set the table up but Im not sure what I can use to hold up the letters that say "GUEST BOOK QUILT". I have the twine and clothespins, and my letters done. My original idea was to use small tree branches but I live in an apartment complex and all the trees around me nothing will work. I thought about a picture frame but I need it to be at least 40"x35" and I dont know where I can find one that large. Looking for ideas please!!
