Start with 8 x 10 piece of cardstockScore ever ½ inch on the 10 inch side (score first, it will save a lot of time)
Cut into two inch strips on the 8 inch side.
Cut those strips in half at 5 inches
Fold each strip in half, mark at ½ inch from the right on the open bottom end (the fold at the top)
Cut at an angle from the top left corner at folded area to the mark on the unfolded area (1/2 inch in from the right side)
Add tape to both sides of 4 of the pieces. Tape together with the points all pointing the same way.
I did a LIVE on Facebook and created a gold Poinsettia. Hope this is helpful.
