some of the first quilts i made for my two grands were mostly faux fur front with minkey backs. because of 3-D applique used, i decided to machine tack instead of quilting. i just made randomly placed small circles, frestyle, twice in each spot. held fine, no threads to hide, cute little "bubbles" seen from the back. still fave quilts and holding up perfectly with no tearing out at sites of machine tacks.
