To make one house you will need :
1. 6 foam sheets (any size you prefer) + extra for applications
2. Thread and needle or a sewing machine
4. Some cardboard. It doesn't have to be very thick and strong. We recycled some boxes that toys, puzzles etc came in . Cardboard sheets has to be just few mm smaller than walls of the house.
5. Whatever you like to use making design on the house. We used glitter glue and foam sheet.We started with cutting out windows and door on the sheet for front of the house. Then we made a design on each of the walls. We cut out different shapes from foam sheets and glued and sewed them on.
Foam sheets are so soft that they need something to help them standing up straight or the house will bend to all directions...Foam sheets are very flexible, they won't break. We stitched the cardboard to the wall with a quick X stitch at one random place, just to make sure it won't slip off the place. Once that is done you can close the last side of the ceiling. We stitched it by hand as it is impossible to bend the cardboard to fit in for sewing machine.
The house is very flexible! It can't hurt even the smallest darlings - it is super soft! Your small ones can carry it around as they please because it is very light!
