Last week we learned how make quarter square triangles. This week we will be combing triangles from half square triangles and quarter square triangles together. Combining these triangles will create a pinwheel block.
Since we are more than halfway through our sampler, I recommend checking your quarter inch seam allowance. A true quarter of an inch seam allowance is what is needed for the sampler blocks to make them come out correctly. If it has been a while since you changed your needle I would also put a new one in.
Next week we will continue on combining quarter square and half square triangles to create a patchwork block.
