My daughter wanted to hang some fabric she bought as a wall hanging. Rather than poke holes in the wall thumb tacks or something, I designed this fabric clip based on my tarp clip (http://www.thingiverse.com/thing:2202140) I CADed up earlier.

Use 3M command strips on the flats of the wall mount to bond to wall without damaging paint. Mount to wall with narrowest part of the opening facing down. Push fabric into wall mount with locking pin. Use 10.5mm dia. pin for thinner fabrics.
