Simply Crochet are supporting Granny Square Day 2019 by offering a free pattern booklet, free square patterns, special Ravelry discounts and more. You can find Simply Crochet on Instagram here and see all the tagged squares here.
You can get involved by taking a photo of a granny square you’ve made, crop the photo into a square so that the granny square neatly fills up the entire space. Then upload the picture onto your Instagram account using the hashtag #grannysquareday2019.
