Being dyslexic I'm not great at actually counting, so casting on for either knitting or crochet is a bit of a... process. After speaking to a few friends it turns out that I'm not alone. So I present the Count It Out marker set- so you easily split that cast on into manageable chunks, or count where you are in a pattern repeat.
These markers come in digits 0-9, in either red or black matching beading.
