How to make an envelope advent calendar
Choose some paper for your envelopes.
You can get really creative here. You can use the same color and pattern for each envelope, or you can mix-and-match.

Pick from:
-Use plain 8.5-inch (29.6-centimeter) squares of paper to label your envelopes with. On the cardstock, get one square of watercolor paper.;
-You can use solid-colored patter, patterned paper, or even double-sided paper. Scrapbooking paper is great for this, but so are kraft paper, old book pages, wrapping paper, and origami paper.;
-Print out a variety of envelopes and choose some as desired. If you're making the advent calendar for a child, you may want to make the envelopes either beige paper or white paper.;
-Many people enjoy making envelopes that include small numbers after letters, though they may not be as popular in future years. A large envelope will be easier to make, unless you need more money to press from.;
