Love your videos.is there avideo which goes along with this blanket pattern? Amanda Reply Val October 16, 2019 at 10:07 am Thank you for the pattern… off work as I tumble downstairs and have broken my leg so will have a go Reply Pauline June 15, 2020 at 9:01 am 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? Reply Pauline June 16, 2020 at 3:40 pm 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!
