You will be knitting the house in the following manner:

First, you will knit the floor, 4 walls, and roof pieces in a stockinette stitch pattern.
Next, you will add a fabric door and windows to one of the walls, then seam the walls together.
Next, you will add cardboard for the floor and stuff the house.
Lastly, you will add the roof to the top. You can also optionally add a chimney and “smoke” to the roof.
