Depends on the tool . I have not the equipment nor knowledge to forge steel so my athame was purchased . My wands have all been crafted by my own hand and some other alter items have been as well .
Some stuff I can make and craft others I can not .
Not a blacksmith - how do you expect me to make that ritual knife!?
I let the professionals work their own magic. Cloth stuff however? I have that handled. Never paid for an altar cloth, anointing cloth or w/e else. I also paint my own stuff....
