Some splits get used pretty fast (I make my own splits, and much prefer deeper amounts of paint to those teensy ones - what, they're like less than a cm deep?!), and some I never do, even though they seemed like a good idea...haha.
Maybe cut those ones you don't use up? Put them back with their mother cakes, or rearrange the colours?
I had a kryolan pink/interferenz pink/intf gold/yellow split - made before I'd really understood that the intf are really too sheer to be paired with the bolder kryolan - and have only used it maybe a half dozen times in the last year. I just separated it and now that space is ready for a new split! I may take apart my kryolan green/neon green/yellow/gold split, too - used to use it for leaves, but I have a DFX green/lime that I looooove now for leaves!
Gina, do you use cuts from your 32gr and 45 gr pots together? I want to make a new split, but that would be cutting into both sizes, and I haven't quite wrapped my head around how to do that
