I have a friend who is a grief counselor for children. She helps the children make quilts from clothes and the working on it with the child helps immeasurably. Have the clothes washed by the owner because the smell of the detergent is part of the rememberance -- she uses large pieces from shirts and pants and arranges them in a simple pattern of rectangles so the child can help by sewing and tying the quilt.
This will be such a blessing to the partner.
