This free pattern can be found on the Red Heart website under Building Blocks Throw. The pattern calls for worsted weight yarn and is in the traditional Lego colors. I chose to use the colors from the Friends line of Legos.
This was a very easy throw to make and you can easily customize it to your liking.The hardest part is sewing on all the dots because you have to make sure they all line up so they look like Legos.
