This Fool's Square quilt block is half the size of the traditional 10" block we normally see for the design -- a petite scale that makes the pattern suitable for a wallhanging or a baby quilt.
Fool's Square is similar to other star-motif quilt blocks. Some are actually identical, but known by different names because their patchwork is designed with varying placements of color value (contrast).
Choose three fabrics for each Fool's Square. Sew with an accurate quarter inch seam allowance, because even small variations can throw off the dimensions of small blocks.
Block corners are made from half square triangle units. The cutting chart below lists the correct size required to make units for the small block, but consider using slightly larger squares and then cutting your units back to the exact size after assembly.
When you trim-back, use a square ruler with a diagonal line from corner to corner (like Martingale's Bias Square). Align the diagonal line with the unit's diagonal seam, trimming two adjacent sides at once to the correct unfinished size (in this case 1-1/2" square) and making sure each represents exactly half of the unit.
