as a shower gift I received a " no sew fleece blanket" it's really cute. you use that thick fleecey material and tie squeare knots all around to hold it together. If you go to a discount fabric store maybe you would be able to find inexpensive fabrics to do this with. If you search on any search engine (i used google to find) a bunch a different directions come up.
you could also make baskets for movie nights for the 19-20 ish crowd, put microw popcorn a couple of sodas, some candy etc.. they don't have to be large and you can get cheap baskets almost anywhere.
cookie mixes in a jar.
"gift certificates" to have people over for dinner at your house. There are plenty of inexpensive dinners to make, or even have just a dessert night at your house even cheaper
I hope this helps, my prayers are with your husband I hope he is on " the road to recovery"
Blessings!
