This is probably a really dumb issue with a simple solution, but I don't have carpet.jar in the file! I've looked everywhere an ran everything and there is NO carpet.jar. Please help, I really want to use this mod!

If there is any more information needed please say, I will gladly provide it.

You get the jar from here, https://github.com/gnembon/fabric-carpet/releases

Sorry About my stupidity. I just realized how to use the mod.

Or from here https://www.curseforge.com/minecraft/mc-mods/carpet
