FREE Crochet Blanket Pattern: By the Sea
You are viewing this pattern in UK terms.
- Using Colour A
- Foundation: Ch 70 + 3 for turning.
- Finally, fasten off and then sew in the ends.

Adapting the Pattern
Alternatively, if you would like to make this blanket bigger, you just need to double (or triple or more) the length of the chain. You must then do the same with the rows. So for example, if you have doubled the amount of the chains, you would also double the amount of the rows.

Hi want to make this blanket. Very much a begginer. Love your videos.is there avideo which goes along with this blanket pattern? Amanda
Thank you for the pattern… off work as I tumble downstairs and have broken my leg so will have a go
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?
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!
