I have two. One is for finished quilts and the other is a studio journal where I list out what needs to be done each month including deadlines etc. and then note what has been completed or moved to another month. The studio journal also includes a list of my current UFOs, ongoing tasks and shows I'd like to enter for the year. That journal is an old hard cover composition book and I've been using it for the past 4 years.
The finished quilt journal is in a looseleaf notebook and I do a page for every quilt I finish. Each quilt page includes: an overall photo; information on kind of batting used; any special techniques that were used; finished size; date completed; and current location if known or if sold or gifted- the name of the recipient/purchaser.
Additional information for show quilts includes:
Appraisal value if the quilt was appraised. Shows it was in if it was shown and awards won.
