Suggestion for getting started making mouth calls:
You can order materials needed from suppliers (Pioneer is one of them).
1) Call frames (adhesive-backed) in standard and small ...(youth/kids frames if you want them, too).
2) Latex in proph, .003 (two or three colors,...natural, green, gray/black), .004 (a couple of colors,...natural, yellow),...thicker latex available, but not necessary.
3) A couple of colors of tapes,...lots available.
Everything has minimum quantity orders.
You can get a jig from someone, but they are not necessary. They have pro's and con's.
(I am not trying to sell you anything here, but if you want a starter kit with complete instructions on how to make calls, take a look at my kits in the turkey call classifieds)
