One of the very large guilds in my area, 300+ members, make quilts for university students who come from the foster care system. Every 2 to 3 years they make about 125 quilts. These students come to campus with very little of their own possessions to dress up a dorm room or to simply dress their bed. Most students have family who help supply sheets, pillow cases, blankets and so on. These young adults do not have family supplying these items. . Although I am not part of this quilting guild, I work on the campus where they donate.
Check with any campus online site and see if they have foster care grads and contact that office. Bet they would be pleased to take your excess quilts.
