boy, I cannot see a thread or two with my eyes.....I just do my best to keep the l/4 inch.

I cant make a STRAIGHT 1/4 in seam- so a scant 1/4 inch is definite not favorable in my lifetime.. !! So scrappy Here I come!!

Ty...I just ignored using scant and carried on with my reg 1/4" and so far so good lol fingers crossed.

Here's a tutorial on this board that is very informative.

I say consistency is more important.

As long as you are consistent through out the project and you are not matching someone elses blocks you are fine with 1 plain 1/4" seam.

I use my 1/4 inch foot and move the needle position over 1 notch on my Bernina for a scant quarter. The Bernina 1/4 inch foot does do a beautiful, very consistant 1/4 inch seam.

Consistent throughout the project. Only way I can get it to work. If I start scant, I finish scant. It doesn't say scant, I line up the 1/4" on the presser foot and keep the seams at 1/4".

As long as all your blocks sew to the same size it doesn't matter what seam allowance you use. It's better to be consistent so seams will match up.
Sewing a full 1/4" and then a scant 1/4" and then something in the middle, nothing will match up that way.

When I see "scant", I scram! :)
