I used to ice skate a lot.
Don't bother with the scarves because they are a danger on the ice. But matching fleece hats and mittens are nice. I would also recommend ice skate tote bags. You can see a copy of the shape used here

I would make sure as someone advised to check out the price range to make sure you can make a profit.
