Took me 4 tries at various online and brick-and-mortar stores to find dye-based double-end markers for the tops' chatter-work. The ones I got are Le Plume "primary color" set. However, they aren't as bright as what I was expecting (don't really seem "primary"). Have had less success finding Tombow, which is the other brand I've heard recommended, have only found water-based. Anyone have an online source? Been making tops for the local County Fair.
