This is the latest pair of cards I've done with the technique.
The pink one, as anyone who knows me will understand, is WAY outside my comfort zone! I really don't do pink, ever. I can probably count on my fingers how many times I've done pink cards in the 15 or so years I've been cardmaking.
To start, the card bases are topfold, more or less standard notecard size- 4¼x 5¾.
I made two panels roughly 4½x 3½, so I had extra for trimming to neaten.
Double sided adhesive sheet is added to some copy paper- you could also use patterned paper you don't use- then the strips of cardstock are added over that. It's easier to work on a diagonal, Jennifer said, and she's right. It's not easy to keep vertical lines perfectly straight, as can be seen in the lower edge of the pink one. Yeah, I had to go there!
For the purple one- and that took a lot of photographing, my camera wanted it to be blue, lol- I used the 'offcut' to add to the lower half of the card.
For the pink one, I made a new panel of vertical stripes. Won't be trying that again. I neatened the top edge with a strip of glitter card.
On the purple card, I used foam tape behind the panels, and I did the same for the top pink panel. The bottom panel is added straight to the card front.
I'm going to enter this over at Pixies Crafty Workshop, for her Snippets challenge, as all the cards are totally made from snippets!
