Blankets are so much fun to sew, in all shapes and sizes! I've made a free tutorial on how to sew one, and you can use it whether you're making a baby blanket, security blanket, patchwork blanket, or even bedspread. 

Here's the file in Swedish.

And here's the pattern (for the patches) and tutorial on how to sew in English.

For the above blanket (with purple binding) I used size M on the patchwork, and for the blanket below (with dark blue binding) I used size L on the patchwork. 

All fabric are jersey from Elvelyckan Design.
