I have treated myself to a blocking board and a copy of The Granny Square Card deck, and have slowly started working through the cards.
I feel like it is getting me to really ' level up' my crochet skills. Each card gives you the pattern for a different square. The cards are numbered with the squares becoming more complex as they go. It has helped me slowly build up my confidence about what I can do, and my crochet is getting more and more neat and tidy with each square.
I highly recommend the card deck, and i might get the other decks if I am still enjoying it when I have gone through the entire deck.
This is the one I got if anyone is curious. If ordering online check that you are ordering the genuine set with the barcode on. There are a few places selling a bootleg version that looks similar but has cards that are not the same.
