I was going to suggest Staples too. I have brought them stuff to laminate that was large than 8.5 x 11 but it was around $4 I think

Just a question -- did the cutting out hand prints take a long time? I saw this craft on Pinterest and am scared to do it for 5 dcks because the tracing and cutting sounds like it will be very time consuming. Was it that bad? Or did you just do it for a couple of kids??
