Here's my magic pinwheels that seems similar to the new pinwheel templates that are so popular now.
I found a charm pack at Walmart to test this out. I used 25 charms (5 per row) and added a 3" border.
I put clear tape on my ruler and traced the lines from the instruction sheet.
This is the first time I've posted with multiple pics.....I'm hoping everything shows up ok
This is how I did my template.
This shows the ruler lined up on the fabric
I'd like more variation, but didn't want to overthink this test!
