I know this post was last year but I've started a jack's chain....I'm stitching my 9 patches with the sewing machine and then hand stitching the triangles in and then the hex - my problem and question is the fabric wants to go to the triangle for pressing but at the tip of the triangle there is way-way to much fabric piling on top of the seams....what do I do? Hope you understand my question...and have a solution...
