I don't any more but did for a number of years to supplement my income. I sewed for a little shop in a tourist town and made children's kilts. Darling, easy and boring, but the money was a blessing.
Later, I made canvas covers for futons for a local store. I made crib, twin, double and even some kings. Not hard but hard on my machine. Each had zippers on three sides but that got to be an easy-pesy thing todo. Can you imagine how long a zipper is on three sides of a king? Good money. Paid for my kids athletic shoes, marching band trips and music lessons for a good number of years.
My advice is work for a store or business. I tried the craft show circuit and did not make enough to account for my time and investment in product.
