blue pigma pen
Why I am not impressed with them.
I contacted the company, and was informed that they were NOT designed for using on fabric.
I made the quilt in 1995 - perhaps they have changed since then.
What I may have done wrong - I wrote over and over on the writing - and it may have soaked into the batting - I used Mountain Mist polyester batting.
The label on the back is pale but still (barely) readable.
