What a meaningful investment of time and talent you’re heading up. That’s wonderful.
If I were leading, I’d make kits. Precut all the fabric with a little leftover uncut for goofs, and pack it neatly in a gallon or two-gallon ziploc bag with thread, pattern, cheap seam ripper and maybe a small pincushion with pins. That way each person has everything at the ready and can just get busy sewing when they arrive. Have them put their name on the kit and all supplues back before leaving.
I would choose simple patterns like you have in mind. Even jelly rolls you make with your own selection of fabrics would be quick, and kids or newbies like to complete projects in just a couple sittings.
Good point about checking the requirements of the organization you’re donating to. Isn’t Straight line quilting easier than tying? I’d leave the quilting to those with that skill . Ties can be itchy, in my experience.
