Heirloom mentors can teach one-on-one, in small groups, or both - whatever fits your space, your craft, and how you like to teach.
If you only have room for one student at a time, one-on-one is simple and personal. If your space and supplies can support more, group sessions let you teach several children at once, each paying a per-child rate you set - which often means stronger earnings per hour than teaching solo.
Each child still brings their own parent or guardian. In a group setting, parents are present but not expected to participate hands-on unless they want to - so you can focus on teaching without doubling your materials for every adult in the room.
There's no minimum or maximum group size. You decide what your space and supplies can comfortably handle, and price accordingly.
