The space behind my chair was just the biggest bit of wall space that could take a design wall.
Decide what size to make your design wall
I used some leftover packaging (extra thick corrugated cardboard) and duct-taped the pieces together to make one big rectangular-shaped board.
Choose and/or construct your backing board
Once you have a board of the size you want you need to cover it with some sort of material that will help your quilt blocks stick to it without pins.
Attach your batting
Note: This bit is totally optional – you can absolutely make a design wall free-standing if you like.
Attaching the Design Wall to the wall
The final size of my design wall is 58″ wide by 36″ tall. I can already see it is going to be so useful for many different steps of the quilting process.
