If you've had a chance to look at the new Stampin' Up catalogue you'll notice a few samples of open ended envelopes like this one. They're very simple to make and you can follow this formula to make one any size you need. It's a great way to use up that retired DSP. Multiply the with of your card by 2 and add 1-1/2". This is how wide your DSP or card stock needs to be. For an envelope with 1" flaps measure the length of your card and add 2-1/4". This is how long your DSP or card stock needs to be. Score 1" across the top and bottom as well as 1/8" on each side of the card. If this is as clear as mud I've included a video tutorial.
