I'm encouraged to hear some reason and compassion finally coming through. Sometimes other people's actions really hurt! We have the choice of how we respond. We can only control ourselves. Your brother is valuable, precious. He's not you and aren't you glad.
Last night, "The Middle" had a scene about a gift of hippy style bright yellow jeans. Her response was hurtful. She'd told them what she wanted, why they picked bright yellow jeans, I don't know. She found a use for them, all rolled up behind her back in the chair at work. They still love her.
I agree with some of the posts. Ask him about his actions with aunt's quilt. Then if he still wants one from you, explain to him your feelings about making and giving him the quilt. Explain your hurt if he was to reject or abuse it. Then let him have a stake in it: pick out and pay for materials and pattern. Make this an opportunity to bond with you brother.
