Measure the dried pine needles into a spice grinder or small food processor, process until it's a fine grind - you can leave them a little rough, or bring it down to a powder. Place in a glass bowl.
Measure all remaining ingredients into the glass bowl
Mix until well combined and all ingredients are well distributed.
Check for consistency - I like it fairly dry, using ¼ cup of oil... but some like a wetter consistency. Add more oil if you like!
Transfer to an airtight jar.
Notes
To use - Use a clean spoon or mini scoop to take a bit of scrub from the jar, scrub onto wet skin. Rinse well!
