I know this is an old thread- I hope you guys still keep an eye on it! :) I have a problem with the adjustable ring constantly opening back up on me... is there a way to secure it once I have pulled it to the size I prefer? The project I'm doing now requires several polka-dots and the center of them...
Alternative to a magic ring: When you crochet rounds in a chain stitch, crochet over the 'hanging end' too. When you're done, pull the 'hanging end' to close the hole in the center.
