I love this fold, can you tell? I've made several :-) This one is using paper from the It's My Party DSP Stack with mint and white strips on the back. Here are some measurements for you ~
Start with a 3" x 8 3/8" piece of 2-sided DSP. Score at 3", 4", 6", and 7". Do a mountain and valley fold, also known as an accordian fold with the strip. After you determine whether you want the fold on the right or left side of your card, you will cut a triangle off one side. I lined up the 3" fold line with the cutting groove in my Stampin' Trimmer, then placed the opposite corner on the 1" mark of the trimmer. Hold your breath and cut! (The ladies in my class were very nervous about getting this right. I would highly recommend trying it on a practice piece of paper first!)
Here is the next potential stumbling block ~ Glue it to your card layer with the folds down to the bottom half. Your straight edge should be in the middle of your card. You will need to trim off a little along the side, as this will be slightly wider than your 4 x 5 1/4" panel. Wrap a length of twine, ribbon, or a 1/2" wide strip of paper across the cut edge. Now glue it to your card base, then decorate. Ta da! You did it! :-)
This flower and the surrounding stamps are from our new set called Love and Affection, available next week. I used Blushing Bride and Mint Macaron here. The flower center is from Botanical Gardens Framelits and the black center is a candy dot. I stamped the flower with Blushing Bride ink onto Blushing Bride cardstock, then fussy cut it out and attached it with a Dimensional.
"Thanks" was stamped with Black Memento, using the soon-to-be-retired set called Another Thank you. Wow, I'm going to miss that one!
Let me know if you have any questions about this. Once you try it, it will all make perfect sense. It is a bit of a puzzle at first. OK, now go try it!
