To illuminate the snowflake, select string lights containing 100 bulbs. Drill holes just big enough for the lights to fit through (for our lights an 11/32-inch hole was perfect) and spaced about two inches apart along the frame of the snowflake. Starting with a hole near the center of the snowflake, insert the lights working out toward the points, then over to the next set of points and back toward the center, then out again, repeating until you've inserted lights as desired around the entire snowflake.
There are several options for displaying the snowflake, such as hanging on a wall near an entrance, hanging it from a front porch or a tree or staking it in the ground. To hang it on a wall or front porch, use a screw or nail appropriate for the wall type or porch material and attach a picture hanger or screw eye to the back of the snowflake. You can use fishing line to suspend the snowflake from a tree or front porch (the line is relatively transparent and will be nearly invisible).
