K.A.
My twins LOVE the soft fuzzy blankets my sister made for them. AND I just made a set for my friends twins. They are so easy. Buy 4 different very soft materias about 2 yards of each. (front and back for each blanket)
Put two together, cut 6" or so strips all the way around, tie the front and back strips together and there you have it.
I also got a frame with a poem about twins in the center of it from my sister in law. that was my favorite gift. You can put a picture on each side and the poem is in the middle.
