I made another of these envelope scrapbooks and I will be giving this one to my mom when I get all three kids Spring pictures from the schools. These are very easy to make and you can make a few pretty fast once you get all of the measurements.
On this scrapbook I used the Designer Series Paper from the Sale A Bration mini called Delicate Dots. This paper has lots of nice spring colors and patterns.
The directions are to score an 8 1/2x 11 piece of cardstock at 2", 2 1/4", 6 3/4", and 7"
The inside is three business size envelopes, sealed, and then cut to 6", 7", and 8". The inserts are cut down by 3/4" so they slide easily in the envelope. Measure your envelope and cut the paper to fit and the embellish the envelopes. The hinge is made by cutting a piece to fit between two envelopes and snailing in place.
