Maybe if you would've cut the mold on the side and then taped it to keep the wax in, the candle would come out. Since you do your own molds you could try that. Just a thought. Thank you for your videos and forget about your accent, I hear myself in you, I'm Cuban.
Thank you for watching! Yes you can make a mold out of cardboard just keep in mind a few things; it won’t be a shiny piece, what ever lines and imperfections the cardboard would have will show up on the mold piece.
Yes all wax will work, in this case it will be treated just like all embedded. Meaning this doesn’t need a wick it’s more for decorating the candle or to be used as a melt. You could put a wick on it if needed by inserting a whole in the middle and passing the wick through.
