The Ultimate Marking Pencil is a wonderful marker for dark fabrics! It stays on – doesn’t even smudge – and washes off or even better your iron will erase it! It’s a solid form of our Ultimate Pounce Powder, formed into that solid by wax which does not leave any residue behind when removed. The whole pencil is a marker, it won’t dry out, you don’t get a refill for it you just use it and sharpen it when needed until you use it up. The more you stick to using it on dark fabric the longer it will last because the less you will have to sharpen it. It’s easy to sharpen, use the slightly larger than standard size sharpener that you can easily find in any make-up isle or school supply isle in your local department store. It doesn’t go through the Full Line Stencil screen but makes a perfect complimentary tool for the Pounce Pad. Use it to touch up chalk lines that were not fully transferred. This is much easier than trying to realign the stencil and reapply the chalk. Improvise if needed to turn corners or fit borders, trace hands, sign names, etc. For clothing they’re great for marking button holes or darts. You’re going to love this pencil!
