poster board or heavy cardstock for base
Cut out the template, punch holes, and glue the colored pieces on top of poster board pieces. Place the belt over the leg holes so brass brads look like part of belt. Assemble by pushing brads through lower holes on arms and legs. With the leprechan in arms/legs down position, tie string/floss through top holes of appendages, connecting arms to arms and legs to legs. Use a longer piece of string/floss to tie arm string to leg string.
Punch a hole in top of leprechaun's hat to insert loop for hanging. Tie a golden ring (old pirate treasure?) if you like, to the bottom string for easy pulling.
If your leprechaun's legs/arms get stuck when pulling, try loosening the brads a bit.
