I'm just throwing out some questions here.....(no picture so I'm just guessing on what could be the issue)
-Did you cut the patches using templates, or using a sketch of the rhombus on your cutting board?
-When you cut the (solid) piece of fabric into the 4 patches, did you switch diamond patch one with three, and two with four on the blocks before reassembling the pieces for the new 4 patch diamond (made of 4 fabrics) ?
(You pretty much have to cut and rearrange all the blocks and lay them out before sewing the 4 patch blocks.
My first JP was made with batiks - ha! Not so smart - try figuring out where (and how) a patch goes when it falls off the design fall - orientation, right side/wrong side. was a bit challenging, to say the least.)
-The diamonds you made - when you say they're not the same size, could it be because they stretched out of shape because of all the exposed bias?
Really, the last is the only thing that should have an effect on the size of the block
Trying to think of something else.
Any chance you could post a picture of the two blocks?
