I am in the process of making 4 patches for a disappearing 4 patch. Before cutting my block measures 8.5". What size should it be when it has been cut and reassembled?
Thank you.

You loose 1/2" for each cut + new seam. So if you make 2 vertical and 2 horizontal cuts, you would loose 1 inch each way. the reassembled raw block would be 7.5", and 7" when sewed into the quilt.

Thank you so much,PaperPrincess.
I tried one block and when it was cut and sewn back together, it came out to 7 and 3 eights". I will trim them to the size of the smallest block once all are done.
Your reply was prompt. So nice to be on this board. Someone always comes along quickly with an answer or suggestion.
Thanks again.

This continues to amaze me at the number of people who provide quick answers and even links!
