Pattern Details:

  • I used Lion Brand One Pound Yarn (worsted weight) for this tutorial. You can use any yarn and crochet hook appropriate for that weight yarn.

    Note: For a beginning chain, I like to use a larger hook for hte chain, then switch to my regular hook size for the remainder of the project. In this example, I did the beginning chain in K/10.5 (6.5mm) crochet hook and switched to G/6 (4mm) crochet hook for remainder of the square.

    It is so hard to print out a copy of your FREE pattern. In fact it is so frustrating it makes me feel like I don’t want to bother. I keep trying because I love your products your recipes, your patterns and you. Please please try to make it easier for us to print the pattern out when it’s free. Thank you.

    • Kristin Omdahl says:

      Thank you so much for loving my patterns and recipes! I understand that ads and the format can make printing more difficult sometimes. Offering them free on the website means I can continue creating and sharing patterns with everyone at no cost. For those who’d like a printer-friendly version without ads, I make ad-free PDFs available on Patreon and in my shop. That way, there’s an option for both — free access online, or a convenient printable version for those who prefer it. I truly appreciate you taking the time to share your feedback, and I’m grateful you’re here creating with me! xoxo, Kristin

    I found the picture on Ravelry. Ignore my previous comment, but it would still be nice if the picture was with the pattern. Thanks for all your work.
