Although the process was very uncertain, I'm super happy with how my pieces came out.
Best to have an idea going in as to what colours and designs you like. There's little instruction beyond 'mix your ingredients together and then go for it', but if you have a vision in mind the instructor is very helpful in suggesting the steps to take to achieve it. They didn't have dried flowers available in my class, but there is colour, shimmer, gold flakes, and some stickers (I reckon you could bring your own things to add if you really want).
The space is small but sufficient, and keep in mind you'll have to pick up your pieces again after 24 hours of drying. But overall I really enjoyed the experience and the end product~

A super fun and reasonably challenging experience.
After some initial instructions you're all set to tuft away, with the instructors coming around with suggestions for how to make your rug turn out better. I'm very satisfied with how cute the rug came out, even with all my wobbly lines. Though there's a lot of yarn colour options, you are limited by what they have available so choose carefully~
