For those who are/want to be involved in making a yarn blanket for EdgarAleNPie this is your crochet thread! I'll post patterns and advice, and hopefully so will other crocheters! Here's a basic Granny square:
1/ Ch2, 4tc in 2nd ch from hook. Slst to join.
2/ Ch2, 3tc ch1 in each st around, join w slst (12 sts)
3/ Ch2 turn, 3tc ch1 3tc in gaps (this makes a corner). Join w slst.
This gives you the square shape. As you increase, the number of gaps to crochet in between corners will increase. Keep increasing until it measures 6" or 15cm - think that's usually another 2 rows?
