The snowball quilt block is super easy – you can make them any size! You start with a square of any size and add small squares of any size to each of the four (4) corners. In this tutorial, for a finished 6-inch quilt block, I started with a 6-1/2 inch main fabric and added 2-1/2 inch squares to each corner. This gives a 1/3-1/3-1/3 proportion to the edges of the quilt block. If you’d like, you can make the corner squares larger or smaller, depending on the look you are going for. Play around and have some fun with this quilt block!

Materials
- One (1) 6-1/2 inch square of fabric
- Four (4) 2-1/2 inch squares of fabric
- Thread
Tools
- Sewing machine
- Iron
- Ironing board
- Rotary cutter
- Cutting mat
- Quilters ruler
Instructions
- Start by cutting out your fabrics for your snowball quilt block.
- With your smaller squares, press them in half diagonally.
- Place the smaller squares in each of the corners of the larger square. Make sure the fold line is diagonal to the corner, as this will be your stitching line. Here I have pinned the smaller squares in place.
- Go to your sewing machine and stitch along the fold on each corner.
- Here is the stitching in progress. Always remove your pins before you get to them!
- The smaller squares are now all sewn down in each of the corners.
- Trim the excess fabric from the corners. Using your quilters ruler and rotary cutter, measure 1/4-inch from the seam line to the outer edge of the quilt block. (NOTE: Make sure to trim off the outside edge, and not from the inside.)
- Here is the snowball block all trimmed and ready to be pressed.
- Press the seams to your preference. Want to know more about pressing seams for quilting? Read our article on how to press seams. Here is the finished snowball quilt block, ready for a quilt!
Notes
If you are using printed fabrics that have a definite direction to the print in your corners, pay attention to the direction when placing the smaller squares on your larger square to make sure that all of the prints are going the same direction. It can be a bit tricky!

Here is a sampler of four (4) snowball quilt blocks together. I love the way the corners match, forming a four-patch. You can have fun using different colors and making different smaller patched blocks across your quilt.

What does it mean to ‘snowball’ a quilt block?
Snowballing a quilt block is taking any size square or rectangle and adding smaller squares to the corners of the block, sewing at a diagonal across the corner.
Can I use precut packs to make this quilt block?
Yes! You can use layer cakes (10-inch squares) with charm packs (5-inch squares) or smaller corners using mini charm packs (2-1/2″ squares). You can use charm packs with mini charm packs. In the tutorial, I cut 2-1/2″ lengths from a jelly roll piece, which is a precut strip of fabric cut to 2-1/2″ wide. Using precuts makes this a super simple project – the cutting is already done! All you need to do is sew!
