Okay, a good old lead pencil will do just fine, but a pacer gives you the kind of accuracy you need when making patterns.
Think about it, if you use a thick lead pencil it may add 2 millimetres to your patterns. This may not seem like much, but if you continue to trace your patterns in this way, over and over, eventually that 2 millimetres will lead to a lot!
And an added bonus... A pacer normally comes with an eraser on the end, so it crosses one piece of equipment off the list! An eraser in absolute pattern making staple. We would all like to think that we are perfect and won’t make a mistake. But we will. So always have an eraser in arm’s reach.
