I want to make a mold of my big toe to make gummi toes for a give away for a tow truck. Can anyone help? Answered

You can't make gummy candy out of an alginate mold. Alginate has a water base and would just mix into the gummy candy. You could use alginate to make a casting of your toe in another material like a low melt wax or plaster. Then you'd use that plaster or wax toe to make the silicone mold.

Instructables has a number of explanations of body casting and gummy candies.

Short version: use silicone for more a more durable mold; use alginate for a cheaper one.
