I try keep anything i share at 50 gc. But I've noticed what I receive is less and less. I used to get 45 gc now I'm only getting 30/35 gc. I'm with the charge less get more downloads overall thinking. And I loath the read permissions!
If it gets too costly i go buy the pattern or find it elsewhere. Before I found here I am overwhelmed by all the patterns on facebook.
Though some are that big and intricate that 300 coins might be worth it. But I doubt I'll ever need the pattern or open them. My ADHD keeps me needing smaller works. So, all the close to free are good for me.
