My notes of the rainbow net (up to blue, haven't finished the purple part yet)
I think I made trebles instead of DCs in round 1 of the net, but that's the round that's not being properly stretched so maybe that's an improvement.
I'm really curious how long it will take to crochet the second net, because the trial and error part and the stretching out after every round sure took its time.
(This is not a finished pattern or anything. Sure, you can try it, but it's very possible there are mistakes or parts that can be misunderstood. These are my notes so I can crochet the second net without checking the proportion after every round)
(First 3 rounds are from naztazia.com)
