From a handful of unruly grannies, stitched up just for fun:
To a nice, bright, little baby blanket:
The two granny patterns are:
Never Ending Granny - the white solid grannies and the grannies with black squares
Bouncing Ball Granny - the corner grannies with black circles
The grannies are put together with ILTY Limelight and an H hook. I used the join as you go method. There are many video tutorials on YouTube, such as the one below, but I suggest that you do a search for them and find one that suits you best. The border is simply rounds of granny stitches and a final round of double crochet.
I like the Never Ending Granny Square. There is a pattern on Ravelry that uses it in large white yarn, trimmed with a dark color. Squares are big and makes an afghan quickly. Thinking of making one for the camper.
Your baby blanket is so cute and bright. Have you given it to the mom yet?
