This hearts bobble blanket is made using hdc and bobble stitch, with a border of cluster stitch around each square before joining together. Then another row of cluster stitch around the whole blanket to finish.

Pattern is written in English US terms with abbreviations for UK

To create a blanket with 12 squares which will be approx 27 x 36 inches you will need:

300g of dk 8ply coloured yarn and approximately
100g of white or cream for the edging.
I found that a 100g ball made 4 squares, with some left over.

Each square will measure approximately 8.75 inches long and 8.5 inches wide with the cluster border.
