This is a lap blanket or throw worked in 100% cotton so it has some weight to it and drapes beautifully, using a striking combination of colours. I have kept the stitches relatively simple, treble and double crochet, but I have included a very basic inset mosaic section to add variety. I have chosen to use the inset technique so that there are not lots of ends to deal with. Inset mosaic crochet works two rows in the same colour. Work is turned at the end of each row with the unused yarn carried up the side of the work. Pattern is written in English using UK terms.
