At least 4! Yup that is right 4 of us, the 2 husbands and the two of us. Amy had an old Grandmother's Flower Garden Quilt that she wanted to square up so she could get it quilted and use it. I have a huge quilt table in the basement and told her she could come down to square it up if she wanted to. Joey and Amy came yesterday and it took all 4 of us to get it straight. The guys had a lot of input and helped us by making sure it was square and held the rulers steady. It seemed as though the more you looked at it the more it was off some place. You can read Amy's post about the quilt and see more photos of the process here.
We had a great time working on the quilt. I hope she gets the borders on it soon and gets it finished up so we can all see it. Now we have one more to do so come on Amy get that edge torn off so we can get it done.
