I do have to ask the following. If we make 3+1 for one spot, does all 4 dolls have to be the same design? In other words, in creating I am worried my supply stash may not be the same for the design I make for each doll. Also, can I choose to use say 2 diff dolls (or 3 or 4) for each spot? Hope I didn't confuse you on this.
