Here is a Celtic Knot Christmas Wreath.
I made it using 1/8" plywood and some fairy lights.
I recommend you burn this with full power for the border but half power for the interior using the backward layer in the svg. Then you can take it out and flip it and then put it back into the board you cut out to cut the front without burning the wood or using protective tape.
here are the lights, but I am not sure I would recommend them.
