Ah, sorry, but you can donate a maximum of 8 sketchpads total per month! I'm not sure if I made things confusing with my comment above about the donation limits not needing to wait a new comment? I can't reward you for more than 8 setchpads, so please claim your rewards for the rest (if you posted them in the collection post, that's fine!) next month!

I see you say this is just the first half but since I'm online right now here's the rewards for these in the meantime :)
