This is an afghan that I made with a random pattern I came up with from the top of my head. Not sure if it was already done, or if I had seen it before, so Im not saying its my very own pattern, but the idea of the pattern came to me and I decided to make it. Anyhow, here's the easter afghan that I made!
But basically, it's done like this -
Chain how ever wide you want it to be but in multiples of 3.
for the first row, all double crochet stitches.
for the 2nd row, do 3 double crochet stitches, chain 3, skip the next 3 double crochet stitches, then do 3 double crochet stitches, and repeat that all the way to the end.
Then keep repeating rows 1 and 2 over and over, ending with a solid row at the end, and add your border and that's how you do it!
A tip on keeping the blanket straight and not lomp sided, is on every row, chain 3 then skip the first stitch, and do your other 2 double crochet's. I have found that method the best way to keep your blankets from getting lompsided when working with a row instead of piecing it together like for a granny square. This stands true for any time you do rows no matter what pattern you use.
