Recently, and I can't remember which blog I read this on, someone posted about how they just started using a 1/4" foot for their piecing. I didn't know such a thing existed, but knew I needed it, since my 1/4" seams are probably closer to 1/2".
I got one yesterday, and I'm in love. Seriously, perfect seams. And mine was only $7 from Amazon!
I really could have used this for my quilt along quilt. Oh well.
