Beginning Mold Making - Plaster Thumb Keychain


Who doesn't want a key chain that is a spitting image of their thumb? Seriously though, in this introductory class participants will learn how to make an alginate mold of their thumb or finger and cast a duplicate digit out of plaster.

If you aren’t feeling the finger keychain you are welcome to opt for a fancy finger stand for proudly displaying your extra extremity on your mantel or desk! Each attendee will leave with a replica of their thumb or finger that will be attached to a key chain or a FFS. 

This class will be DJ'ed by you so please message Maker Mountain Studios with any guilty pleasure songs you don’t want to request in public. Your secret is safe with us. Curious about our guilty pleasure? We have a soft spot for the 1997 classic MMMBop.

We are offering another version of this class on September 15th at 7pm, check out Drink and Make Stuff.

Techniques that will be covered:

  • •   Proper mixing of alginate
  • •   Making a waste mold
  • •   Proper mixing of plaster
  • •   Casting with plaster to get fine details 


Wait, what does that mean?!

Alginate- a mold making material, made from seaweed, which is safe to be used on skin.

Cast- the process of pouring the liquid plaster into the alginate mold of your finger.

Fancy Finger Stand/FFS- it’s really just a stand for your plaster finger.

MMMBopis a song written and performed by the American pop rock band Hanson and released as the lead single from their debut full-length studio album, Middle of Nowhere, in 1997. The song was nominated for two Grammys at the 40th Annual Grammy Awards in February 1998 and is the band's most successful single to date. "MMMBop" was phenomenally successful, especially for a debut single, reaching number one in 27 countries including the United States, the United Kingdom, Germany, Australia and Mexico. Bet you didn't think you were going to learn that much about a 90's pop song while trying to plan an awesome day out. Thanks Wikipedia! 

Plastera hard material made by the addition of water to powdered and partly dehydrated gypsum.

Waste Mold- a mold that is destroyed during the process of removing your plaster finger or thumb.



Q. Is there an age requirement.

A. No, but participants must be able to sit relatively still for a few minutes while we make the mold of your thumb.
