Since this was posted, a TQS member has shared some important safety information. It seems that foam board can be flammable and should be covered by drywall. There is a simple solution. Instead of foam board, use acoustic insulation sound board. Since it is pourous, it works just fine with pins. As an added bonus, it contributes to the absorption of sound transmitted from the exterior or other rooms.
When Christa moved into her new home, her top priority was getting her quilt studio up and running. One of the first things she did was build a design wall, and she took step-by-step pictures so she could share the process with you.
(The quilt on the wall is from Christa's Rainbow Weave quilt kit.)
