Mine is digital but I intend to convert mine to paper. My grandmothers were both quilters, one kept notes and the other did not.
The one that kept notes had two binders - one was a photo album, and the other was all her graph paper patterns, sketches, notes, even some flyers from her Guild. I didn't know these existed until about a year ago when my aunt brought them out to show me.
It was very moving to read through it because she had left personal notes in there too; including a couple of paragraphs about the last quilt she made and how she felt giving up quilting due to her failing health. She passed away about a year after that was written and that was indeed her last quilt. It was so hard to read but so moving...I'm glad she took the time to write it all down.
My aunt has indicated that I will inherit those two binders some day, since I'm the only quilter in the family (so far). I would love to have my own binder or two to add to it, to pass down to someone else when it's my turn to shuffle off this mortal coil - I don't have children of my own but both my niece and my nephew have shown a lot of interest in sewing so I am hopeful one or both of them will take up quilting some day, or at least have a strong enough interest that they would cherish these things.
