Traditionally, the snowball block was constructed as a 9 patch, with HST units in the four corners of the block. Most modern quilters use a much easier technique to construct this block, which is outlined below. This method, called the "Quick Corner Method," is preferred unless you intend to showcase a fabric in the center of the block. In that case, you might want to refer to the 9 patch method.

Rotary Cutting Instructions
How to make a Snowball Unit using the Quick Corner Method:
- Determine the finished size of your unit. Use the chart below to find cutting measurements for the individual pieces.
- On the wrong side of each small square, draw a line on the diagonal with a marking pencil. (Or, you could just press them in half on the diagonal to mark the line.)
- Position the small squares on the corners of the large squares as illustrated below.
- Sew a threads width to the OUTSIDE of the marked line on each small square. Trim 1/4" seam allowance to the outside of the sewn line.
- Gently press triangles open.
