If it's a gift, who you made it for
The event it was made for (wedding, baby with appropriate date)
Size of block, sashing, borders and quilt
Hand or machine quilted - I usually include that on the label, too
Whose design? If it's your own design, say so, eg 'using EQ6 with xyz blocks"
I keep mine in a scrapbook with a picture of the completed quilt and thank you note (if it was a gift) from giftee
