yes it has sizes, but as a starter like me i didn't know what size i got haha. I think the one i got was size 36 and 40, 36 gives a rough, fast work while 40 gives better details. so the higher the number the finer the needle is.
I DON'T HAVE THE MATERIALS /sob They're not very big on crafting these in the philippines. I have some white felt, though, half a yard. I feel like sewing a lot of bunnies, 'cause I don't know of any other white animals. ;w;
