So this was a lot of fun to make. Here is my take on the challenge:
I made my own envelope out of kraft cardstock. I loved the way Melissa used kraft and how the white popped off of it! So I got out my Martha Stewart scorer and made an envelope with it. Easy Peasy.
I stamped the back like I did the front. I made my own envelope tie closure using some buttons and brads.
Here are the other supplies that I used:
Embossing Powder (Zing Red Glitter, Ranger Seafoam White)
Stamps (Strawberry Patch, Postmarks, Mat Stack1, Strawberry Patch Sentiments)
I also made a card to go with the envelope (which is the reverse of my normal process).
Thanks for looking!
