Fun flip-flap folio with no dies, no complicated cutting or measuring, using materials you probably have right now.
You will need two empty boxes from facial tissue with a center top opening. Kleenex has the right style, Puffs has a side opening that won’t work for this project. Additional supplies: two sheets of copy paper for hinges, scissors, glue, and whatever you desire in the way of decoration.
Open the empty tissue boxes at the short end. Cut off the four flaps on each end, saving the two larger flaps from each end, on each box. You will be saving eight larger flaps, each with some design on them. The eight smaller flaps with only printing registration marks can go into the recycling bin. Remove the clear film from the center and discard.
On the first box (lemon print in the photo) cut the smallest part of the tissue opening off. You will be able to open the box completely flat.
On the second box (blue print in the photo) cut at each fold line so that you have four sections – top, bottom, and two sides. Trim the long edge of each piece by about 1/4”.
Attach the sides of the second (blue) box to the flap from the first (lemon) box.
Hinge the top (blue box) to the bottom (blue) to the center of the folio (lemon box). You will need two hinges that are 8.5” long and about 2” wide. Fold each hinge in half. Attach one half of one hinge to the top and one half to the bottom so that they open like a book. On the opposite side of the bottom, the side with no hinge so far, attach a folded hinge to the underside. The other half of this hinge attaches to our folio.
Use hinges to attach the saved flaps (lemon and blue) in a waterfall pattern in the center of the folio (lemon). Do the waterfall last so it covers the hinge attaching the bottom/top “book” to the folio. The hinges for the waterfall flaps should be cut from copy paper and be about 4 1/4” long and about 1 1/2” wide. They can be narrower (less than 1 1/2” wide” but not wider or you will run out of space for the waterfall.
