that is great!
i just wished my s/machine liked very thin materials . . . for some reason it won't cooperate, no matter what i do to change the settings. i might try it w/interfacing/thicker backing.
if you were to do a colored one . . . would you use a coordinated color backing?
edit . . . yes, i thank those people that sew them for a living . . . bet they can do 2 in 1 minute!
