I am attempting to put together a 12 block quilt using the disappearing pinwheel block. The design originally called for them to lay side by side with no sashing or cornerstones. I began with 2 10" squares and they've finished at 10 3/4". I now need help trying to figure out which size I need to cut to make either mini pinwheels or hst for sashing between the blocks. Could you please point me in the right direction with cutting sizes? Either design works for me (I think). Here is what the blocks look like so far.

I'm not sure I understand the question. If you could draw a picture of what you have in mind, it could help someone who has the talent to calculate block sizes for you. Your blocks are very pretty!

Ok, I will give this a go.
Firstly I would sew a tad wider seam so the blocks end up as 10 1/2" squares - finishing at 10" in the quilt, which is an easier measurement.
Your sashing could 'finish' at 2" - (making five 2 1/2" HSTs) or you could make two 5 1/2" pinwheels (5" fin) - per each side of the blocks, plus extras for the cornerstones. Don't know if you could really call that sashing , but I wouldn't want to be making 2 1/2" pinwheels though.
I guess it depends on how busy you want your quilt to look, but I hope I have helped.

I like those blocks! Those colors just glow!

What "finished" size do you want for the mini-pinwheels?

Theoretically speaking, if one makes HST units from squares, one cuts the square 7/8 inch larger than the size you want the finished unit.



Example: If you want a 2 inch HST unit, cut the squares 2-7/8 inch.

HOWEVER, many of us have much better results if we cut the square one inch larger than the result wanted.

Example: Cut two three inch squares to finish to two inch HST units and trim.

If you wanted a 3 inch "finished size" mini-pinwheel - Cut the squares 2.5 inches for the HST units - trim the units to 2 inches - then each HST will "finish" at 1.5 inches -

You already know that it takes four of the HST units to make a pinwheel.

well i'm a sucker for 1 inch black sashings in between blocks with black in the fabric.

I'll keep math out of my answer because math and I don't along. LOL. But just wanted to say I love your fabrics, especially the turquoise and black combo.

I'd probably use solid sashing and smaller pinwheels as corner stones. Your sashing would just need to be the same width as your pinwheel cornerstones. You could experiment a little to see what size pinwheel looks best to you with the bigger blocks. Then you don't need to resize your big blocks. I'd use a fabric that reads as a solid that would frame the big blocks and help them pop. The cornerstone pinwheels would still be scrappy like the big ones. I love the blocks you shared. The colors work wonderfully with each other in each block. Keep sharing your progress!
