The answer to this question probably depends on the quilter, but I'll ask anyway!! My dealer is having a 15% off sale on Bernina bobbins and feet. I just purchased a bunch of fabric for a new project, and I don't want to buy both bobbins AND a foot, but I could use some bobbins and I've been drooling over the #57 patchwork foot for a while. I use the #37 for piecing just fine though, and I'm wondering if the #57 is worth it.
Does anyone here use it? Is it fantabulously better than the #37 for accuracy? I don't want to succumb to a pure 'want' while I'm trying to watch the budget.
