This is a new size for me, I decided to try a few a little bigger than my 3 1/2 x 5 inch books I have been doing. I am making myself one similar to this one, have a lot of the papers cut already.
It measures 6 x 6 inches. It includes 2 cardboard covers, the front cover is decorated with 3 ribbons tied into a present like design. 14 double-sided patterned cardstock pages, 7 plain cardstock (3 of which are tabs), 5 small envelopes (2 red, 3 white). There is also room to add more.
This 2nd book is for sale in my Etsy Shop here.
