I'm impressed that the feedsacks left by the mother of the lady's husband is going to be made in to something that might become an heirloom. What memories I have of having a new dress for the first day of school made from feed sacks that my mother let me pick out! On a bed in my spare bedroom I have a quilt that my mother appliqued flowers on each block that was cut from a (bleached) white feedsack and finished in 1942.
The price sounds reasonable for all the work the quilts will require.
