Mosaic Overlay 101: Project 3 - Buttonholes

Mosaic Overlay 101 is a series for people who are new to Mosaic Overlay crochet techniques. This project shows how I make buttonholes. It is in preparation for a July 2022 CAL (Crochet Along) project to make a Triple Stripe Plaid Pillow.
I use buttons in all of my pillow designs so the inserts can be removed for laundering purposes.
