Does anyone have a foolproof method for sewing non-nesting seams together? Seams where the seam allowances both go in the same direction. I've tried fork pins which are wonderful for nesting seams but marginal here. Tried Wonder Tape....a 1/4" double-stick tape that washes away and is supposed to not gum up the needle. It holds pretty well but I get a slew of skipped stitches after stitching through the tape. I'm putting my Dear Jane blocks together and the sashings and cornerstones are 1/2" so accuracy is important on this small scale. Any help would be greatly appreciated!!

why not press the seams in the sashings/cornerstones so they nest? seems like that would be the easiest most accurate way to go- if they are sewn down to one side you just clip them to the stitching line so you can fold them in the other direction.
when i paper piece and have 2 pieces come together where the seams are in the same direction i poke a pin straight into the point of the top piece- then line up and poke straight into the bottom piece making sure they are perfectly joined- holding the pin straight up & down i then carefully pin the 2 pieces together on each side of the straight in pin- that technique may work. place a pin directly next to the seam- then line up with the bottom piece seam- and pin on each side of it then you can remove the center pin

If the straight down pin and fork pins to secure don't work for you, though they always do for me, I would have to suggest hand basting first. It takes a little longer but is worth the effort considering all the time you have already put in to the project. I want to see it when it's done!

Those intersections can be really fussy. Sometimes it works for me to pin parallel to the seam and as it approaches the needle, withdraw it very slowly. I also sew with an open toe foot so I can see the pin get pretty close to the needle first.
But in all actuallity, I don't mind twisting the seam. Makes quilting in the ditch a bitch, but if you press well, you may never be able to tell. I would not clip the seam.

I would clip so that you can press in opposite directions. Jenny Beyers does this and it turns out great.

I have never heard of this. Sounds like a great idea. How far below does she clip? Thanks.

Have you tried temporary fabric glue?

I flip the last inch (more or less) over and iron it well but have never clipped it. It has always worked for me.

I'm also a clipper--just below the 1/4"--comes out perfect every time!

Tacking works really well and there won't be any pins to get in the way or
under the needle. Try to tack under the 1/4" allowance so you can remove
the tack afterwards. Check Rhonda's tutorial here.
