What are you most proud of? This is so pretty and perfect for my mother for Mother's Day. What advice would you give someone starting this project? Practise with this Granny Block mug rug before starting a large project. You can see how your fabric combinations will look whilst also making sure your 1/4" seams are to size. The pattern includes full colour diagrams and easy to follow instructions. All you need is a little background fabric and four or five charm squares.
