Frequently Asked Questions

How many granny squares do I need for a blanket?

It depends on your square size and your target blanket size! A 6-inch granny square blanket that’s 48 by 60 inches needs 80 squares. A 12-inch square blanket of the same size needs only 20. Smaller squares mean more weaving in ends and joining… larger squares mean faster going but fewer opportunities for color variation. Most patterns will tell you exactly how many squares to make and at what size. If you’re designing your own, measure your square and do the math based on your goal dimensions.

What’s the best way to join granny squares?

There are so many options and each gives a different look! The join-as-you-go (JAYG) method attaches each new square as you finish it… no separate seaming step. The slip stitch join creates a visible decorative ridge. The flat single crochet join is clean and sturdy. The whipstitch is simple and quick. The mattress stitch gives an almost invisible seam. Try a few on spare squares before committing to a full blanket. The “right” join is the one that works with your squares’ style and your aesthetic preferences.

Can I use different yarn weights for different squares in the same blanket?

In theory yes… but in practice, mixing weights creates uneven squares that are very difficult to join neatly. Squares from different weight yarns will be different sizes, and a blanket made from squares that aren’t the same size ends up puckered and lumpy. If you want a scrappy multi-yarn blanket, stick to the same weight across all yarns… different colors, textures, and even different brands are fine as long as the weight is consistent. Gauge swatch your first square and aim to replicate that size in each subsequent yarn.

How do I keep my granny square blanket from curling?

Blocking is your answer! After joining all your squares, wet block the entire blanket by soaking it, laying it flat, and pinning it to even dimensions. This sets the stitches and prevents the edges from curling or rippling. For acrylic, steam blocking works well. A border around the edge of the blanket also helps stabilize it significantly… one or two rounds of single crochet or half double crochet around the entire perimeter pulls everything together and gives the edges structure.

What size hook and yarn should I use for granny square blankets?

Worsted weight yarn with a size G/4mm to J/6mm hook is the most popular combination for granny square blankets. It creates squares that work up at a good pace, are easy to see and count, and create a substantial, cozy blanket. DK weight with a smaller hook makes smaller, finer squares. Bulky yarn makes bigger, faster squares. For scrappy blankets using leftover yarn, just stick to one weight category and use the hook size the yarn recommends… your squares will be similar enough in size to join without too much fussing.
