I never would have thought to cover little matchboxes in bookbinding papers but I saw a blog post from Parvum Opus (great inspo for fancy little paper-and-glue objets) and had to try it.
Just cover two boards 1/8 inch bigger all around than your matchbox, then glue them to the box. (It’s not hard, but the blog post gives you the details if you need them.)
Blammo, now you have fancy little matchboxes! If I ever give anyone candles, this would be a nice addition. (Do I need to try candle making next???)
