  • 2. For medium tree, repeat Step 1 but set aside one 4" half ball for a future project. Stack and adhere remaining half balls together. Adhere two 1" balls to top of tree.
  • 3. For smallest tree, repeat Step 1 using one each 3", 2-1/2", 2", and 1-1/2" balls. Stack and adhere all half balls together. Adhere two 1" balls to top of tree.
  • 4. Following manufacturer's instructions, mix Smooth Finish prior to use. Wearing rubber gloves, completely coat trees with Smooth Finish using spatula or flat paintbrush using methods outlined in Steps 5 and 6. See Photo 2. When using spatula, apply small amount to foam and spread evenly in all directions, working finish into foam cells. When using paintbrush, load material onto brush and spread onto foam, smoothing lumps as you work.

  • 5. To create textured finish on tallest tree, first use brush to apply coating to crevices of tree, and then use spatula to create small, overlapping ripples in coating. Apply small mound Smooth Finish™ to tree and then another overlapping first. Keep working with coating until tree is covered and fairly uniform. Let dry completely. Use sanding block to lightly sand raised areas to create smooth appearance as shown. See Photo 3.

  • 6. To create super sleek finish on smaller trees, use brush to smooth out coating as you apply it. Apply first with spatula, then smooth with brush, or simply use brush to apply coating to entire tree. Let dry completely. Use sanding block to create ultra-smooth appearance.
  • 7. Use drybrush technique to apply mint green paint to tallest tree. To drybrush, dip flat paintbrush into paint and rub off excess onto paper towel. Using side of brush, lightly brush across raised areas of tree to add color, leaving recessed areas bare. Let dry. See Photo 4.

  • 10. To create tree trunks, cut top 4" from 9" cone using foam cutter or serrated knife. Use remaining 5" section to create base for tallest tree. Cut top 3/4" from 4" section; use remaining 3-1/4" section to create base for smallest tree. Cut top 2-1/2" from 6" cone; use remaining 3-1/2" section to create base for medium tree.
  • 11. Coat tree bases with Smooth Finish™, let dry, and sand surface smooth. Paint bases silver; let dry.
  • 12. Insert toothpicks halfway into tops of bases. Use glue gun to adhere trees in place.
  • 13. Embellish trees with metallic yarn. Pin one end of yarn to top of tree and spiral down around to bottom. Secure yarn end with pin at bottom of tree.
  • Tip
  • 1. For added sparkle, use glue gun to adhere tiny crystal gems over surface of each tree base.
