This is a FREE PATTERN in PDF format for a crocheted Bobble Cowl. It is fun and easy to make it! And as it has many holes which you can use as loops for buttons, you can play with it’s shape as you want. Here are some versions, but I am sure you will find many more.
Enjoy!

Uses 150 gr. of a bulky wt. wool/alpaca blend and a J or K hook, whatever size you need to get gauge.
