I checked nookplaza and it lists only one item with 3 variations for each and lists them as customizable, though... we may have to wait until June to know for sure.
Actually I forgot that DIY items do have all their customization options listed (Life works like the in-game catalog, no customization on store items but all the different main designs for DIY) If it's true, that pretty much confirms they're craftable then.
EDIT: I found out this only happens in June so this is a BIG SPOILER!
So, I was in Harvey's Island and I was going home but I realized that Willbur dialogue was a little longer than normal, so I read it. I could barely understand it between so many slangs but:
it seems that you now can sell stuff to them or give them delivery to us later?? Wow that's amazing, it will be awesome for when you are on rare islands. But since when we have this? When was this added? I am so confused why I never heard anyone talking about this dkdk
