Wool (Leeds 15)

I make crochet hearts for Leeds hospitals. When a baby, child or adult passes away the lovely Nurses press one of the hearts to their lips and gives the heart to the bereaved parent or partner. They then kiss another heart and that is placed with the person that has passed. The bereaved person then has a lifetime keepsake that will hopefully give them comfort. Am looking for any scraps of wool to keep this lovey gesture going.
