Wow, more quilts end up with battery acid on them than I ever dreamed!
When our sons were in high school, they both played football; the oldest only for a couple years, but the younger played all through middle and high school. When he was a junior I made my first "completely done by me quilt" - it was an irish chain in the school colors (red and white) and had 4 appliqued cardinal heads (school mascot), and the center had the name of the school and the dates of the school year. I took a piece of the backing (muslin) and had all the team members and coaches sign it with a Pigma pen at a team dinner. Well, thankfully I never got around to applying it to the back of the quilt, because it ended up in the back of my younger son's SUV with...you guessed it ...a leaky battery. It has several holes in the backing. Fortunately I still have that piece with all the signatures on it, and some day I'll get around to fixing it (this was about 9 years ago!). He'll get it back eventually.
