She can't read patterns so there is no pattern for this scarf as such but I can tell you how she made it.
This Lego scarf is a great beginners project, it uses all the basic crochet stitches and incorporates bobbles which give it texture.
Step 1: Crochet your Lego blocks, she used this YouTube tutorial. The length you want your scarf will determine how many blocks you make.
Step 3: For the border she did a round of single crochet around the whole scarf and then a round of double crochet.
Step 4: Now all that's left to do is add a fringe to each end of the scarf.
Pretty simple right.
