I love to make my own envelopes. All you need is a template , a glue stick, and decorative paper. You can use old calendar pages, childrens books, cardstock, really anything you want to make your envelopes.
Select the template you want, trace it onto your decorative paper, cut it out, fold it and glue the edges.
I have many envelope templates which are "laminated" and I keep them in my crafty binder.
