pinwheel quilt block

Here is the pinwheel quilt block pattern and tutorial I have promised to show you in the Snowman Quilted Pillow Cover and how to piece Half Square Triangle (Easy Quick Method). Finally, I’ve gotten it done within my busy schedule between crafting and renovating my new house. YAY!!!

This simple Pinwheel Quilt Block is constructed by 4 pieces of Half Square Triangle (HST) units. Arrange HSTs in such a way to resemble a pattern of revolving triangles, just like a pinwheel.

Hope that you will try it out soon!!!

I am currently working on my daughter’s full size super single blanket, hope to be able to update you on the progress soon. The new house is waiting for a DIY on a plank wall, build-in cabinets, furniture, and decorations, and we will be ready to move in. Can’t wait!
