Always generate descriptions with a text editor (MS Word, Open Office, etc), give them a logical name and save them and then cut a paste them onto Etsy (or whatever site you're using)
I usually do but today I was lazy and I just lost ten minutes work when my browser crashed.
Also this make them easy to access when you want to use them as templates.
Another reason to do this is Etsy's spell check is comes up with some questionable "corrections." BTW you would have thought that it would recognize "Etsy." It does not.
