Crochet pattern for a mermaid tail blanket. Want to make a fun “lapghan” for yourself or as a gift? These warm and snuggly blankets will help to keep you warm when watching TV or just relaxing with a good book. The shell pattern has the look of overlapping fish scales. Choose a sparkle yarn to add to the fun. Other good choices are yarns with blue and green tones.

The upper part of the blanket is crocheted in the round without seams. The toddler version is made in the round from the beginning, while the two larger sizes start out flat and then are joined in the round after 20 inches (51 cm). The tail fin is made separately and attached with a slip stitch seam.
Instructions for three sizes are included: toddler, child and teen/adult.

I would rate this pattern between easy and intermediate. You need to be able to follow the instructions for a shell pattern and to do some decreases. But don’t worry, step by step photos are included.
