THE YARN

I chose to make this in fun rainbow colours for St. Patrick’s Day using Yarnspirations Caron Cotton Cakes in Calico Flowers.

The Caron Cotton Cakes by Yarnspirations is a great choice of yarn if you are beginner.

• Has some grip which allows for great control over your yarn.
• Benefits of working with cotton but less splitting than with some tradition 100% cotton yarns.
• Large ball is great for many beginner projects.
• Recommended hook size is 5.00 mm
• NOTE: This pattern calls for a 6.50 mm for body of hat be sure to use the size in pattern NOT the recommended size on yarn.

DESIGNERS NOTES

• This crochet slouchy hat is worked top-down in increasing rounds.
• Colour changes are made every 3 rounds
• Contrast band is made with a smaller sized hook
• This pattern is for an adult
• Downloadable PDF includes 6 sizes Newborn to Adult XL
• This hat can be worked counting rounds or until hat measures 9.5″ – 10″ in length
• Easily shorten or lengthen this hat by working less or more rounds
• For beginners – 2sc in next stitch means you are working 2sc into one stitch.  It is these stitches that increase the size of the hat.
• Note:  This pattern is written in standard American terms.
