The idea all started with two pieces of foam leftover from (presumably) the brand new air conditioner.
It has adhesive sides but I used the hot glue too.
To make this you need:
Foam
Hot Glue
Scissors
Measure Tape
Fabric to cover sofa
INSTRUCTIONS:
You figure how you want your couch to look and cut and assemble the pieces together and hot glue it or use the self-adhesive foam pieces without the hot glue. Once assembled, either leave the couch as is, or cover it with fabric of your choice; in my case, I think I'll hot glue fabric from old shirt.
