I have recently been going through the same thing! I was cultivating and controlling certain weeds, and then the seasons change and I don't like them.My first Island is literally a sorta abandoed town and fairycore/foresty core in the back, so weeds are helpful to show age, abandonment and foresty areas.
So I do plan on using more, as I am still designing.
I do notice however, that over time the weeds change to one specific style of weed that I am not a fan of? For example, I placed down like the lil grassy weed, but over time it becomes that really big weed? And it takes forever to get to the weed in my bags for the one I want again :/
I've also been using custom weeds not just for that, but to give some variety of weeds.I have recently been going through the same thing! I was cultivating and controlling certain weeds, and then the seasons change and I don't like them.
I have recently been using custom weeds designs to display on the ground. They may not be as nice (blowing in the wind for example), but at least I can control the look of weeds on the ground!
Plus, if people ever visit my island, the real/fake weeds probably won't be noticed!
