These paper trees are as pretty as origami versions but easier to make.

For large Christmas trees, use an adjustable circle cutter to make 2-, 3-, 4-, 5-, and 6-inch-diameter circles from green card stock (for small trees, omit the 6-inch circle).
Fold each circle in half 4 times with a bone folder. While circles are folded, snip off the tip of each piece, forming a very small hole in center.
Place smallest circle on the pointed end of a wooden skewer (we used 12-inch skewers), letting the tip poke through the hole in circle. With a hot-glue gun, dab underside of circle, where paper and skewer meet. Hold for 10 seconds to secure.
Working 1 at a time from smallest circle to largest, slide remaining circles onto skewer; secure with glue.
Insert bottom of skewer into a spool; remove, and cut skewer to desired height (we cut ours to 6, 9, and 10 inches), keeping in mind that only spool should be visible beneath standing tree. Return skewer to spool; secure with glue. Add a dot of glue to top of skewer, and attach a gold bead.
