Pattern writing is not my forte, so please bear with me! This doily is in three rounds. Rounds 1 and 2 are simple ball and shuttle. I used two shuttles wound CTM for the third round. If you find any mistakes, please let me know, and I will correct them. Enjoy!
Round 1:
Rings: 4-4-4-4 (3 picots) RW
Chains: 4-2-2-2-2-4 (5 picots) RW
Round 2:

Note: I just read on Miranda's blog that this doily is actually the first three rounds of Mom's Doily by Nancy Tracy. Thank you, Nancy, for sharing your wonderful designs! I hope I've represented your pattern in a way that pleases you.
