I think it's up to you how elaborate you want to make it. For me, the simpler the better would work best. I take pictures of my quilts but haven't really been documenting them. Keep saying I'll start a journal but so far haven't done it. I'll probably just include the picture, the date of the quilt, and who it was made for. I generally don't keep information on fabric lines, etc. Might include LAQ information on those I send out. Also any notes I think might be helpful.
