Scant 1/4" or full 1/4" seam allowance?

Amen! If the fabric is cut correctly, stitched correctly, and pressed correctly, there's seldom any need for skimping on that 1/4" seam. If the fabric isn't cut correctly, all bets are off.

I usually set my seam guide to a very scant 1/4"...basically, that's about a thread's width away from a perfect1/4". However, RARELY, IF EVER do I sew a perfect seam every time. I mean, really, with only a thread's width of tolerance, how could I be THAT perfect? (I tell my DH and kids that I'm, "perfect," but they all know that it's a snow job.) And what's more, does it really matter? So long as your blocks meet the size requirements, square up and match up with the other blocks, you should be fine.

Bonnie Hunter is one quilt designer who calls for "scant 1/4" seams in most, or a lot, of her patterns. I am going to try to figure out what I need to do/change on the pattern so that I can utilize a full 1/4" seam instead because some of my seams look more like 1/8" seams and I don't believe they should be that thin. And yes, I use Aurifil or other good thread.

Ummm.... except when it DOES! As a pattern designer, I can tell you that it really does matter if you find your perfect 1/4" seam, even on your own blocks. As an example... say you're making a very simple block from a pattern, and it calls for a 4 patch unit to be attached to another piece. If the 4 patch you've sewn doesn't have accurately sewn seams, it will not match up to the square you've cut out to attach it to. You can't blame the pattern designer for that, but it is frustrating for you as the one sewing it. Every single project you ever sew will go faster and smoother in the future if you find out first where that accurate seam is. And the more seams in the pattern, the more that matters. It's not the "quilt police" talking here... it's someone trying to help you avoid future frustration. LOL!

Use what works.If your blocks measure correctly using a full 1/4 in use that.But if you find they are too small back the seam allowance back a little.Use a scant 1/4 in.Make a few test seams to find out.I think of patterns as just a guide.Adjust what you need to to get what you want.....I hope this makes sense.

I teach a Beginning Piecing Workshop regularly. I teach my students that all seams in piecing are a scant 1/4". And, that everyone finds their scant 1/4" seam differently. I have them sew on a 1/4" graph paper to see where the edge of the paper hits when they are sewing just to the right side of the line on the graph paper. When I sit down to my machine, I bump the needle bar position over one notch to the right, and guide the edge of my fabric just inside the feed dogs. 2 students in my current class, bump their seam allowance over 2 notches, but have to use the regular presser foot instead of a quarter-inch foot. Some can do great with guiding the fabric along the quarter-inch foot, but most can't see the right side edge of that foot. Here's a picture of sewing on graph paper to find that scant 1/4".
