I lined all the sides with aqua dot paper (Recollections) and I lined the insides with PTI's berry sorbet cardstock, so as the treats get eaten, you'll see the cute pink. After I die cut the frame with PTI's Pretty Peonies dies, I put some clear cardstock to cover up the window. Then I just glued/scor-taped up all the sides. It was actually pretty easy. The I made the tag using PTI's Make It Monday diecut double up challenge. The image from PTI's Tremendous Treats Valentine is stamped in the negative space.
