Add your file to xcs. if you want remove the offset then you can delete the current one on this file to make it thinner or thicker. this file is for a 6inch  tree of life. 

add your wood to your machine and process. I used 3mm basswood. 

you will get an end product as shown in photo. 

use any string you may have available and tie it to the wood piece. I used fishing string I have. I tied it to 3 sections to have 3 sections to hold my leaves. 

finally, tie the ends of the strings to the leaves you have available to you from outside.
