When I am photographing a quilt for a quilt show submission, when I am auditioning where I want to hang a quilt or mini quilt, or even when I am photographing a quilt outside in low breeze conditions, I like to use painter’s tape to hold up my quilts.
First, I run a piece of tape along the upper and lower edges of the quilt. Then, I make many small “rolls” of tape to stick along the first line of tape that was pressed firmly into the quilt.
I have found that for mini quilts, this is often all I need to secure the quilt to the wall for many months. Note that I am using the delicate painter’s tape from the hardware store. I have not had any issues with residual tape stickiness being left behind on my quilts. I do feel a bit like a “yoga spider” when I do the dance to hang a larger quilt on a wall using this method on my own, but with a bit of persistence and planning, it has been a very non invasive way to temporarily tack my quilts up for photographic purposes.
