i have a singer 301a
as i'm piecing my first "real" quilt, i noticed that no matter how carefully i pin things... my seams aren't lining up. after some arguing with myself and my machine, i started to realize that the two pieces of fabric are not going under the presser foot at the same rate. the lower piece of fabric is going through at a slightly faster rate.
for now, i'm mis-matching my seams to compensate. this is all fine and good for the next hour or so... until we go out to dinner... but i don't think it should be the way i do things long-term.
thanks in advance
