My 630 gives a true scant 0.25" with both the 37 and 57 feet. blocks

turn out the exact size they are stated to be. I always made true

0.25" seams and that scant difference made me off. Maybe the machines

that are stitched out first are checked for this too or maybe it is

just random. When I did the classes for my first Bernina, an 830 in

the 70's we were told to use the edge of the zig zag foot to get the

1/4 and that I did for years but was never as accurate as I can be with

the special feet. The scant seam seems so narrow to me. I wonder if

using the metrosene thread with the full 0.25" would also work since

thr reason for the scant measurement is to allow for the thread

displacement when flattened. Does anyone piece with metrosene to know?

I definitely think "thread take-up" is part of the true 1/4-seam

formula too. Another reason I use Aurifil MAKO cotton for piecing.

It is so fine but very strong, and the bobbin will hold MILES of it.

For the children's garments I sew, I use Mettler 60-wt. (I know, it's

embroidery weight) cotton for the same reasons. I don't use anything

but cotton because if DGD steps on her hem, I want the thread to break

rather than the thread to hold and tear a hole in the dress.

I would hesitate to piece a quilt with polyester thread. You'd be

better off with the Mettler 60/2 wt. 100% cotton embroidery.

I piece with Masterpiece (Supeior). There is very little bulk in the seam and it is very low lint
