A photoalbum isn't a difficult construction. There are a million ways to do one, but I think as beginner, you would want to stick with something simple.
1. Goto the store and purchase a basic photoalbum, ( just a cover with the photo pages) that you like the inside pages of.
2. You will want to make a leather cover you slip the photoalbum cover into.
3. Cut a single piece of leather big enough to wrap around the front and back. Make sure to give yourself enough extra that the binder will slip in after sewing.
a.tool the outside
b. dye the outside
c.If you want to get fancy, glue in a leather liner
4. cut the inside flaps for front and back cover
a. tool if desired
b. dye
c. burnish inside edges
5. Sew the two together
6. sand the perimeter flush
7. burnish the edges
8. apply edge finish
As an example, here is an appointment book I made using the same construction. Same principle would apply to a photoalbum.
I made one side shorter so it would be easier to change notebooks. For A photoalbum, I would make both sides full length.
Here is a leather portfolio I constructed.
