You will need: perler beads (white, pink, dark grey), a hot glue gun (with glue sticks), perler pegboards (a circle and a square one), an iron, and ironing/wax paper.
Step 2: Make the Corner Pieces.
Make the white corner pieces by placing the beads on the pegboard. There are 3 different pieces in one set. You will need 8 corner sets total.
Step 3: Fuse the Beads.
Fuse the beads by placing a sheet of wax paper over them. Gently iron them at medium heat for a few seconds. *Make sure you don't over melt the beads or they will be unable to "snap into place" for the 3D effect.
