I use aluminum foil press the against Asian style items . Simple!
Miniature samurai swords were found on eBay. The flower ( looks a bit like the Japanese crest) was found in the jewelry making dept at craft store ( Beverlys )
Aluminum foil just pressed against item until detail show and then cut the foil out.
Be careful it is very delicate at this point.
I fill the cavity with tacky glue . U can wait for it to dry but I'm lazy so on to the structure it goes
Once dried it's stronger and will hold it's shape. You can use a sharp X-Acto knife at this point and cut out any trim
Let me know if you have any question or better suggestions
Thanks!
