I got this from a crafting list I am on, and thought you may find it fun to try.
Subject: Making a pentacle altar tile
Merry Meet, I sent this to another list (gasp! are there others?!) but wanted to share here too... This is one of the things I made for my altar, I have more but this is the first that came to mind. I am always trying to be a thrify Witch so making tools and items work well for me and cost *much* less than buying, not to mention the energy you infuse them with as you create your items.
Making a Pentacle Altar Tile
Acrylic paints in assorted colors, 2oz. bottles (These you can get cheap at craft and hobby supply stores, they cost under $2 apiece and you can get them on sale, especiall around the holidays.)
Clear shellac in a spraycan or the brush-on kind (acquire at craft/hobby supply store also.)
small art paintbrush (if using the brush-oh shellac, get a larger paintbrush or one of those sponge brushes with the handle, this type of shellac is thick.)
round item to trace (I use the bottom of a can.)
something to put your paints in (old egg cartons work great for this or you can get cheap palettes at craft/hobby stores.)
This can be done to create all sorts of tiles for many purposes, to give as gifts or just to make your own to use or for decorations, trivets, etc. I have used glitter on some of mine and you can use all sorts of items like shells, beads, stones and crystals, fabric, small mirrors, etc.
