I have 60 quilt blocks pieced by my Grandma over 55 years ago. She started making a quilt for each of her grandchildren and did not get all of the blocks set into a quilt top before she unexpectedly passed. I was one of the oldest and my quilt was completed. At my aunt's auction a few years ago I saw these blocks (two sets) and I knew immediately that they were made by my Grandma as they were all hand stitched and I recognized so many of the fabrics used, a good part of which were feed sacks. I will turn 70 this year and material from my first grade dress is in some of the blocks. Grandma had only one eye having lost sight in one from an accident and was hard of hearing but she always had a quilt going or in the frame (for other people).
Now...these blocks are terrible wonky. I am sure she would have worked this out, but I need advice on what exactly to do. I am sure that I will add sashing around each block in an off white muslin type fabric. Do I cut my sashing a certain size and try to ease in; do I take tucks somewhere; throwing them in the trash is not an option. I think they will trim down to 9" blocks. Would trimming them down to a smaller block help? I can't ruin any blocks.
The kicker is I am not a piecer/quilter! I am finishing my first ever quilt top and I see more in my future. I have been around quilters all of my life but I had always said NEVER me
