Thanks for all your kind comments! I think my block looks like some sort of American Indian symbol, but I can't place which one. My grandmother was Am. Indian - I wish I could have learned more about her culture before she passed. (I am the only one in the family that got all recessive gene traits from my father- I look Irish instead of Am. Indian - the rest of my family looks Indian!!! I was always so jealous!)
Maybe I should do a quilt with Indian symbols in honor of my grandmother. I named my vintage Singer 201 after her...
