This is a CreativeBug.com class, but it's easy enough to figure out how to strip together 30 strips from the Robert Kaufman jelly roll and then quilt & bind as desired. I plan to make one for myself since it's so bright & cheery. Could do straight line quilting for a quick finish. Probably could finish in 2-3 days (or 1-2 long days) as long as you keep the quilting simple & bind on your machine.
Better than fresh flowers & not much more difficult. Just make sure to wash the quilt before you bring it to her to reduce risk of infection.
Hope your friend makes a full recovery & enjoys her beautiful new quilt!
