I love a CAL (Crochet-A-Long) and I’ve run one or two a year for a while now.
Here’s where you can find them all. Clicking on the CAL name will take you to the main information with links to all the patterns.
If you’d rather the patterns in a single document, clicking on the pictures will take you to the ebook version of the pattern with the exception of Beyond the Granny and In a Spin which don’t have ebooks.
2016 Fran Mystery CAL (not a mystery anymore!)
2015 Greg Mystery CAL (not a mystery anymore!)
2012/3 In a Spin CAL (Note – some pattern links may no longer be free or available)
That should keep you busy!
