Thanks everyone! I popped on the board and read, with much gratitude, all your suggestions and advice. I did check the math and it turns out the original square size I was working with was typed wrong. I am going ahead with sewing 1/8" seam allowance and notated the mistake on the pattern directions.
thank you everyone- I thought I had to abandon this project and quickly find another ( I hate not finishing stuff). I truly appreciate your help and advice!
Peace,
Deb
