Yes, it can be done if she enlists help from others. But honestly, why would a homeless person want a lap quilt? Small quilts for homeless children in shelters would be useful, but for adults?
Maybe she could consider a drawstring bag that would hold the Bible and toiletries. That would be something that could be used to carry things or perhaps later filled with a few clothes and used as a pillow. Even more useful would be if the bags were designed with straps and could be carried as a backpack.
Bless you for helping her plan her project!
