To make my chunks, I used a small jellyroll baking pan (like a sheet, only with a 1-2 inch raised edge). I lined it with foil then sprayed very lightly with canola cooking spray. Then I poured the wax in and popped it in the freezer for a few minutes (maybe 10?), just until it was set, but still slightly warm in the middle. Then, lift the foil OUT of the pan and onto a towel or something else!!! I took my sharp kitchen knife and scored lines to make the chunks, and then after it had finished hardening enough not to smoosh, I cut the chunks. I picked out several handfulls of the "best" chunks to stick to the sides of the jar. I stuck those to the sides first (and stick more than you think you want because occasionally the overpour gets between the chunk and the glass!). The chunks are still slightly warm and they stick easily if pushed on firmly. Then fill up the container with the less pretty chunks and crumbles from cutting it out. Let the overpour cool til slushy- this is IMPORTANT!!! Otherwise you'll melt your chunk color into the overpour! Fill up the container SLOWLY- it's already full of chunks, so there isn't that much overpour. Tap on the sides of the container (or jiggle it some) to get any air bubbles out. After it's full, arrange any chunks you want on the top (but I really try to do this before it's full!). Keep in mind that the two colors will blend together as the candle melts, so make sure they don't mix to make brown!!! I really like the chunks a dark color with the overpour a much lighter shade of the same color... Have fun! But don't wait too long to cut the chunks!!! Oh, and I've been wanting to try this with some very small cookie cutters also- they sell fondant cutters in the bakery doo dad section of just about everywhere... those would be PERFECT for doing some shapes mixed in with the chunks... Yankme's Gel/ Parrafin line with the embeds and clear overpour got me thinking about those... Can't you just see little leaves or gingerbread men? lol -Kristi
