I am gifting a friend's son with a quilt for his graduation. They are not very familiar with quilts and this is a mixture of light colored and dark colored batiks as well as some touches of red fabric. I prewashed everything with Retayne til the color catchers came out ok. But I wondered if it would be a good/nice idea to gift a bottle os Synthrapol and washing instructions with the quilt. What would you do?
