The By The Sea Blanket is a quick, easy and modern blanket. Whether you want to make a baby blanket or modify this blanket to make it bigger, I’m sure you won’t be disappointed with the results. I’d love to see this blanket being made in different colourways so make sure you tag me on Instagram using @bellacococrochet and #bytheseablanket so I can see! This blanket was designed to use 4 balls of stylecraft special chunky, making it the prefect 4 ball project!

How to adapt

If you would like to make this blanket bigger, double (or treble or more) the length of the chain. You must then do the same with the rows. So if you have doubled the amount of the chains, you would also double the amount of the rows.

          Hi Amanda I do not have a video or this blanket, however it’s only treble crochet so maybe you could have a go at following the written pattern. Good luck 🙂

    Dear Sarah-Jayne, I have taken up crochet during lockdown and have been massively inspired by your website, your YouTube videos have been a godsend! I have chosen this blanket as my first proper project and decided to double it so it could properly wrap around a person so I bought 2 of each colour. I understand doubling the foundation chain from 70 to 140 but not sure I understand doubling the rows. Won’t doubling the chain and crochet 12 rows of each colour use all the yarn? Should I have bought more yarn? Will it look wrong if I just double to chain length but not the rows?

      Hi Pauline

      Thank you so much, it makes me really happy to know you’ve found my videos and website helpful As long as you have bought twice the yarn for this project then you shouldn’t run out by doubling the rows. If you want to keep just four blocks of colour then just double the number of rows from 12 to 24. Another option would be to keep 12 rows as in the pattern, but then repeat the whole colour sequence again so you have eight colour blocks. Hope this helps

        oh yes I like this, thank you! I swapped the white for a meadow green (children with grubby hands don’t go well with white) and will post the outcome on insta for sure!
