Adult Ariel Mermaid Tail

This is a knitting pattern for my Adult Mermaid Tail/blanket. This comes with as an automatic digital PDF file download.

After designing two child Mermaid tail blankets, I was asked to up the pattern size to accommodate adults. This pattern comes in 5 adult sizes from XS to XL.

This tail is knit in the rounds and is completely seamless. It is designed with a cable pattern accompanied with the moss stitch. A very fun and rewarding knit!

Curl up on the couch with a good book snug in your mermaid tail!

I have been knitting for 14 years. I started knitting right before my first child was born. I started with a scarf, moved to a cardigan and then to a baptism gown! I loved to knit, but hated seamed patterns. I started designing my own seamless knit patterns.

I have an electronic systems engineering degree, but currently am at home with my children. I love the challenge of numbers, so writing up my patterns is great for me!

Please enjoy my patterns. They are modern and mostly seamless! Happy Knitting!
