I've been working on her Pieces of Baltimore for about 6 yrs. Organization and concentration are the two things most required. I now have 10 of the 12 blocks done. I work on it while I'm finishing another quilt's binding or if I'm in between projects. It usually takes me a day to cut and label the material for one block and then another day to put it together. I love her patterns and have three of her books...but, they are not for the faint of heart LOL!
