If you have the paper cut, boards cut and predrilled, then the scrapbooks will be ready to assemble in a group setting.
Parental supervision is recommended.
Drill 2 holes at one end of each board. Sand boards to smooth rough edges. Place paper under a board, lining up to fit on board, mark with pencil where the holes are located. Paper punch 2 holes in each paper, following first sheet as a guide. Cut 2 small strings of twine and lace through the holes and make a loop with it so you can turn the pages.
