The Catherine Textured Diamonds hat pattern comes with step-by-step written and photo instructions. Familiarity with the Front Post Double Crochet is helplful, although not required as instructions are available in the pattern. This is NOT a good beginner pattern! To complete this hat, you need to be able to follow written instructions, be comfortable skipping stitches and picked them up again later, creating X's and working in multiple rows at once. Once you get the hang of this pattern, it is not to difficult though, and can be really fun! You will learn lots of new skills that can be used in other patterns too! This pattern provides instructions for 5 different sizes, ranging from newborn to adult! Each size has seperate instructions, so there's no looking at stitch counts in parenthesis! Pattern is written for Worsted Weight yarn. The last 3 pages of the pattern provide step-by-step photo instructions for each size. Full of pictures to help, this pattern is great for an intermediate-advanced crocheter! If at any time you have questions about the pattern, my email address is provided and I'm happy to help!
