Random Stripe Generator :generate random stripe patterns for knitting sweaters, scarves, blankets, etc. It'll give you an idea of what the finished sweater will look like, but it still leaves some unpredictability to the stripe pattern.
Random stripe pattern generated using the Random Stitch Generator, beware it is addictive. It took me a good two hours to get a pattern that I loved, and then I still tweaked it.The finished size is, 36" x 42". J (6 mm) Hook (roughly 7 pattern rows & 14 stitches = 4") I can do this! ¯\_(ツ)_/¯
This site has a random stripe generator which is rather cool. You select your yarn colors, stripe width by rows, and number of rows you'd like to generate. Gives a general idea of what your project will look like. Fun to play with!! Biscuits and Jam
