Do you have a photo for it? Also is there a link to apply?
Edit: I just saw the other comments, I just assumed that Mindful Crochet might be the name of their shop but if it is not they are correct. Even if you credit them you cannot call for a pattern test or distribute patterns made by other people.
I see your new, Here are some rules and explanation of ribblr:
You can not post a tester call of somebodys pattern, otherwise you can get reported.
To post a tester call of your own pattern, you can look for the tutorial on yt
If you are stuck on anything look on youtube or contact ribblr.
Everybody makes mistakes, just trying to help you
you also need a shop to sell your patterns. unless mindful crochet is the name of your shop, you can’t have people test patterns that aren’t yours, that’s stealing
