Before you start with the 3D lace , punch a hole in the middle of the stars using the large attachment of the hole punch. Now fold the 3D lace on one side, punch again with the hole punch and fold the lace on the other side. Punch through here again with a pointed object and pull the chain of light lights through.
Finally, decorate your window with the chain of light , use the shining Fröbel stars as wall decorations during the Christmas season or arrange them with your Advent arrangement.
Have fun crafting!
