There are a number of ways to make a design wall for quilting projects. Some are more expensive than others, some are more labor-intensive than others and some probably work better than others too.
The first method I’m showing here is the easiest, cheapest, and possibly the least satisfactory; but it works.
Quite simply, it’s a vinyl/plastic tablecloth with a fuzzy lining that is tacked to the wall with the fuzzy side out. You can usually get inexpensive versions of these table cloths at big box stores. For even better prices shop the clearance after a holiday when they are getting rid of “seasonal” décor. I recommend that you get one that is not too high contrast because on some the fuzzy lining is so thin that bright colors can show through and be distracting when you’re trying to see how your blocks will look.
This is the type of “design wall” that I have at the moment. I have had a little trouble with pieces falling off, but not too much. I put it in our guest room where I had some wall space and I try to keep something pleasant to look at on it when company is staying in there. Also, the walls in there are already full of tack holes (thanks, former resident), so I wasn’t concerned about adding a few more. (bleh)
Here is another method that involves covering some insulation foam board with quilt batting. It costs more but is still relatively easy; and you can make them any size you like, take them along when you go somewhere to quilt, or use them to display quilt blocks as art.
This version involves the insulation foam, but it is covered with felt and is made more permanent to the wall. It will cost a little more and take more work to install it.
