Sugar'n Cream - BBQ Apron (crochet)
Crochet Dishcloth Patterns: Dishcloths are great to sell as set of 3 to 4, you should be able to get $1 each for them. This site has 25 different patterns for free. I personally like this for beginners. Big Tip: use a cotton yarn, sugar n cream is a brand that is cotton this is great yarn to use because it can get wet and easily washed.
