I made the one in the video tutorial using brand new Stampin' Up! DSP and it is so gorgeous, the stripey design with floral flip side is called Share What You Love and is a huge pack of 12x12 DSP with special texturised finishes. I love it... well almost all of it.
You need just one sheet of 12 x 12, tw strips of 2 x 7 inch cardstock, a couple of pieces of ribbon and some scraps for a tag and some embellishments if you choose to add them. That's all and there are only 6 score lines to put in to create the fab spacious gift bag. It's so simple.
Hope you have fun if you decide to give it a go.
