I managed to get the music quilt sandwiched yesterday. Tried to use the rulers to do STID but that was a bust. For some reason, the quilt wouldn't move smoothly. So I switched to the walking foot. Everything worked fine but when I hung the quilt on the banister, the SID lines are puckered. This was my first attempt at using an all Poly batting. Wonder if that is the cause. Never had that problem with Warm % Natural.
