These are mini houses that GABY got me hooked on! She sent me some and I made templates from them and created 5 for her in return and also some for birthday and raks! So, they are such fun! Lining them up to make a whole city scape would be fab! They are quite small, ranging from 3 1/2" longx 1 1/2" wide to the smallest at 2"x1"wide. Very neat small format!
