i used to sell sweets deco clay items but now sell resin and sweets deco (mainly since sweets deco is falling out of fashion) and let me tell you it is a fuckton of work if you're not autistic about it. honestly, if you have to ask about clay specifics, you already aren't experienced enough it certainly doesn't all look the same lmao (also padico resin clay, i'm assuming modena, is way too expensive and heavy for the most part) the stuff only looks cheap if you suck at making it. i remember 2 years ago i was at a huge local con and a lady was selling similar items but they looked terrible and were made of cheap polymer clay, likely because she assumed she had no competition (she seemed like the type who assumed no one else in the world thought to make that stuff) she kept coming to my table inspecting my stuff and asking me how i made it and she seemed visibly annoyed most of the time, turns out my table was doing way better than hers. all in all though, craft tables, especially handcrafted items, take way more time and effort than standard tables, especially when artists can draw one drawing and then print it out to sell dozens of times. of course art is a skill, but the ability to print the art is invaluable, whether it's into stickers or prints or pins. for crafting you have to make every item by hand and then make it into something someone wants to buy (people don't just want the item, they want accessories, charms, keychains etc.) on top of all that there's huge overhead, for the clay, molds, paints, tools, and for findings, chain, whatever else.(so much went into the item in your pic alone which isn't that great looking) you'll have to learn jewelry making as well. plus, once you sell out, you're done for the weekend and if you sell everything too quickly that's it. i love making stuff and have been for 5 years or so. it's a lot of work and extra work. for me it was and is still a ton of fun, but it's not just easy money regardless of talent.
