1. Here the pages are cut with extra paper at one end to over lap the next page on the back.

2. This uses medical paper tape available at drug stores to butt two pages.
These joins are done after the pages are prepared and cut to size.

3. The pages of this book are prepared and placed in a separate cover which has two folds giving three parts: back, front and an inside flap. You can glue your first page in place and glue the inside flap over it but sometimes it’s nice to leave it loose.

4. This shows the page glued to a separate front cover and covered with a textured endpaper.

One and four are Canson paper, two and three are computer paper with a heavy paper for three’s cover.
