here's how you do the clouds (I'll explain it as best I can): step 1: unlock the magical palette in patterns (unless you already have it) step 2: use the 2 specific one you want step 3: tap the specific area and before that areas been covered with that pattern, switch to the other selected one. (that's about how you do it sorry if it's kind of confusing 😅)
