These make great keepsakes to send to family or friends, or as wedding gifts. And you can make them either permanently closed as a keepsake or hinged to open and close and swap pictures out.
Step 1: Stuff
Cardboard- I used a packing box
Fabric of your choice- I used a good velvet that I cut up a thrift store dress to get.
Xacto Knife and/or Scissors
Elmers Glue- or your could use hot glue for some of the edges if you want more instant gratification
Step 2: Stab
Cut around the area that is marked with the pen, using an xacto or your scissors, then trim the plastic down to be a smooth oval shape, and be sure all the marked edges are removed.
