Here's the dimensions if you want to do it with scissors
In that folded position glue the long inner strip and punch a small hole to tie the tassel (here I have used twine) Glue just the strip - edge of the 1st waterfall piece almost square piece - end to the brad piece at the center. Attach the brads to the cards inner mat and tuck the tassel end under the strip so that it can be pulled and gives the waterfall effect
The base svg, knk and silhouette file are uploaded and can be found under the main tab
Here's the card I made
The waterfall effect
I made another version of the same where I folded the card so the inside of the card. I just twined the twine (ha ha did your tongue twine? Mine did) around the ribbon
