This is a personal pattern created for my own use. I had fun making it and shared it on YouTube on my channel More Than Yarn. This written pattern has not been tested by anyone and is based off of my free video tutorial. This pattern is written out, not a chart, and uses US abbreviations. There are no specific yarns needed but you can see what yarns I used in the video tutorial. Any acrylic or cotton worsted weight yarn should produce a nice square! The average square if using the recommended weight yarn should be about 4x4 inches. Use the hook you are most comfortable with given your type of yarn, I do recommend around 4mm though.
