Here is a simple Dollhouse that can be made from two pieces of foamcore and some scrapbook papers or just tissue paper and old magazine cutouts.
-2 Pieces of standard foamcore or recycled foamcore signs
-glue and or sticky dot type roll glue ( I like the sticky dot type as it does not warp the foamcore as badly, but it does cost more)
-chip brush or cheap paint brush (for applying water thinned glue)
-Utility Knife and or X-acto knife
-Scrapbook papers, tissue papers, stickers, etc
-Ruler or straight edge for cutting
-Cutting mat (to protect table)
Step 1: Cut the Foamcore
First you will need to cut the ends off the two pieces of Foamcore so that they are square. Do this by measuring the shortest width and then make all the sides that size. Use the utility knife with a fresh blade and make sure to go all the way through when cutting.
Now take one of the square pieces and cut it in half.
This will make the top two pieces that fit together. The other square will be the floor.
