I'm practising the 'vintage vertical stripe' Bella Dia blanket, which I want to do as a baby blanket while I'm bored in hospital with poorly baby DS. Going out to get soft yarn shortly.
But I have a problem with my pattern! I'm increasing every row. The pattern says 'always double crochet twice into the same space at the end of the row'. But this makes an extra stitch! What am I doing wrong?!
