Gather supplies – paper and glue or tape. I used glue this time.
Fold roughly 3/4 of the paper in 1/2 leaving about 1/4 of the paper as a unfolded flap.
Fold the flap over.
Unfold and put a thin line of glue on the outer edge of the big end of the paper.
Fold the flap back into place a pressing down on to glued edges to make sure they stick.
Once the glue is dry your homemade envelope is ready to use.
Note: If you are using tape simply bind the tape along the edge instead of gluing it. To seal the envelope use a thin line of glue along the lip of the envelope or use tape to tape it down.
