4 sticks/ $1
There is no DPG added to my incense. I blend the ingredients and roll it out myself (and my boys).
  Once the batch is ready, we (my boys are a tremndous help) roll it into 'snakes' and onto the sticks. 
I use quality Essential Oils and some Fragrance Oils. They are clearly marked for your convenience.
Update: we still make our own dough/punk, but my hands no longer allow me to hand roll them. I am working with another crafter who allows me to use his incense machine, which puts my handmade punk onto the stick.  Everything still done by me.
