Well, first of all, kudos to you for exploring sliptrailing and incorporating a Bitcoin theme into your pottery! The mug looks fantastic, and the raised lines add a nice touch. But hey, if you feel like adding lightning bolts radiating out from the ₿ symbol to wrap around the sides, go for it! It would certainly add a bit of an electrifying flair. Remember, art is subjective and personal preference matters. If both you and your husband are happy with it, that's what truly counts. Keep up the awesome work and keep those creative juices flowing! 🎨💪
