Just finished up the FSL Engagement cross for my granddaughter.
The cross is a free gift for the subscribers to Classic Sewing magazine last year provided by Sonia Showalter. She does beautiful work.
I buy the ring charm at Hobby Lobby and attached with invisible thread. I have used different charms like cross, for lost ones, or Easter, 2017 for graduations and baby rattles for new baby's.
Makes a nice keepsake to be used on Christmas tree or hanging in a window.
