Making the envelopes was super easy to do and I've already started making cards to go in them. :-)
Supplies: Envelope template, magazine, scissors, scorer (to score the folds)
I made a template for an envelopes that will fit 1/4 piece of paper - so the cards I will make will be half a sheet of paper folded in half. You can download my template here. I printed it onto card stock and cut it out.
Then I went through my magazines and pulled out pages that I liked.
I put the template on the back of the page and traced it - I did not trace on the side I wanted out the outside of the envelope.
I had a stack of magazine pages ready to be folded into envelopes.
I used a straight edge and a scorer to score the four fold lines (you can see the fold lines in the template).
First I folded up the two side flaps.Then the top and bottom flap
I put double-sided tape on both of the side flaps and then folded the bottom flap up - making sure that the paper was smooth once it was taped together.
Next you just need to fold the top flap down and you have an envelope. Once you are ready to mail the envelope you can either use double-sided tape or a nice sticker to seal it shut.
When I mail the envelopes I plan on writing or printing the address on a white mailing label and sticking it to the front of the envelope.
Here is the stack of envelopes I made...
and here are some of my favourites.
I have a coffee problem. Mmm coffee.
