FAQ
How many granny squares do I need for a jacket?
It depends on square size and your jacket size. Mikey’s Granny Cardigan uses 54 squares of 6 inches for XL to 3XL. The Glam Granny Coatigan uses 62. The blanket cardigan uses 126 small squares. Your pattern will give the exact count for your size.
What yarn is best for a granny square jacket?
Worsted weight acrylic or wool blends are the most common. They are warm and hold their shape. Cotton gives a cooler, heavier jacket that suits spring. If your jacket is long, choose a soft, drapey yarn so it does not feel stiff.
How do I keep granny squares the same size?
Use the same hook and yarn for every square and keep your tension even. Block all squares to the same size before joining. If one square is too small or too big, remake it. Small differences add up fast across a whole jacket.
Start your first square today, and soon you will have a jacket nobody else owns.
