After my most recent trip, I found my Creek guidebook in sorry condition, cover completely torn off. It seems to be a common problem with these...
I followed this guide to give it a new, hardback cover. Took about an hour and a half, and the only supplies I didn't have on hand were fabric and a sacrificial hardback book to steal the cover from (I got one at a thrift store for $1). I added ribbons for bookmarking
I wanted a color that would stand out in the desert sand, so I went with purple. Here it is laid out
I glued the old cover to the inside flaps,
and added a design to the front.
Some of the Elmer's glue shows through the cotton fabric; maybe get something thicker or waterproof if you are going to try this, or use less glue. I'm happy with it overall though.
