Its still July right? So I can still post a Christmas in July card. Fancy folds are my thing and so is easy. So nothing can be easier than this card. I again saw it on Pinterest first followed the link and saw that it was featured on Splitcoast Stampter way back in 2015. A video can be seen here (427) Decorative Corner Card - YouTube but really this is so easy you can probably just figure it out. 1 sheet of 8.5 x 11 can give you 2 card bases. Though you will need some scrap of the same base color for (2) 1" circles also. I have to admit if you follow the video your card will be a bit smaller. Just a tad. I don't think they utilize the paper quite right. So with my way cut a 11 x 8.5 sheet of solid cardstock in half so you have 2 pieces 5.5" x 8.5" Then on the long side score at 2", 4", 6", and 8". I would glue your layers on before you glue the tube together. So you would need (4) pieces 1.75" x 5.25" solid cardstock and then (4) 1.5" x 5" DSP. You also need 2 1" circles scored down the middle. Personally I prefer an 1/8" border over a 1/4" border. If you want that instead then you would need (4) 1 7/8" x 5 3/8" solid card and then (4) 1.75" x 5.25" DSP.
Glue the DSP to the solid layer and then glue that to the card base. When all 4 sections have been layered run a bead of glue down the 1/2" strip of the base and attach to the other side to make a tube. Flatten card with just glued seam down. That will be the back. Along the front seam glue 1/2 side of a circle to each side of the seam.

Glue the Front embellie to the other half of the circles. This gives it the pop out when you shape the card back into a tube. Basically thats it. Embellish as you wish. This fits in a standard envelope and lays flat yet stands freely when opened.
