The only way I can solve this problem for me, is when joining my squares or half square triangles together leave the first quarter inch unsewn...then start your seam line with a tiny back tack. Helps to "twirl the seams and make the seam lie flat.

Sorry I missed your earlier post. A hammer has been my "Go to tool" in my sewing studio for many years now. Not only works great but I get such satisfaction beating those humps into submission.

I think the pattern that you chose is one that has always had a problem with too many seams coming together. I'd be nervous about trimming a 1/4" seam down. That's not many threads really and with wear, I 'd have concern that seams will come open. Depends on the use of the piece, I guess. But, yes, the tailors came up with ways to corral unruly fabric and the hammer/rubber or wooden mallet is preferred! Glad you found the solution that works for you.

If you try it you will see the cut away area is in a 1/4" seam. In the center there is only a regular 1/4" seam, no lump. Dont cut more then 1/4 V at the end of a seam. I learned this in Home Ec class and watching Sewing with Nancy when she made clothing.

Glad it worked for you!

Fruitloop- I've been using this method for years and have never had the fibers unflatten. Grading the seams works for some things, but I'm not sure you can remove enough bulk with grading to get them to lay good and flat when there are so many seams coming together at one point.
