Sewing an Easy or Casual Single “Mattress”

I’m sure you won’t need my “instructions”, but you might like my idea of an alternative version of this SIY (sew-it-yourself) “mattress” using curtains or big print fabric rather than a bunch of little pillowcases sewn together.

I won’t be able to try this till April, or May, with my upcoming trip. However, I’ve tested the instructions outlined with paper to know it works.
