Instead of paying hundreds of dollars for a chakram like Xena's why dont you just make your own for alittle over 20 bucks. Things you will need:
10 inch circle
primer for paint
gray spray paint that is sparkle
2 by 2 1/4 wood (plywood or oak) oak is stronger
If you dont have a jig saw but you have a hand saw
buy plywood because you wont be able to cut oak with the saw its to hard.
Step 1: Buy a 1 foot by 1 foot 1/4 piece of wood
I got mine at lowes. Just ask the people who work there can they show you where the 1/4 piece of woods are at. You will have to get a bigger piece like 2 by 2 they don't come as small as 1 foot by 1foot. I repeat the piece of wood you will but will be larger then what you need but it will be very very cheap. That way if you want you can make one then one with different design or use the wood for something else.
Step 2: FInd a circle around your house the measures 10 inches across.
I used the cover for the stove it was perfect size.
Step 3: Draw the ying yang design
The was the most difficult part for me. This is what you can do print it out really big and trace it on the wood.
