I was sort of stumped as to what I'd make for this challenge so I started out by making a load of little matchboxes (1.5" x 2") and waiting for one of them to tell me what to do. In the end I decided that I would make a little matchbox shrine of love magic. I guess after seeing all those wee matchboxes together I began to think how cool it would be if an old grumpy witch kept a cupboard full of the little things, each with a different magical purpose.
So here is my wee matchbox shrine of love magic...

Red cotton thread is often used in magic for binding, like keeping a lover. A few drops of red wax to seal the bind.

The match is a hint to the secret inside.

The wee dangly bit on the end is from a pair of earrings I got for a quarter! It has heartshaped locks, keys and stars... all perfectly magical

Inside...

Everything the lonely need to attract and keep a lover.

That little bottle contains a love powder I made based on Oberon's love spell in A Midsummer Nights Dream which includes the first violets of spring and other terribly romantic things

There's a rosebud, and cinnamon sticks, a bit of comfrey root and a lemon verbena leaf which is used in a famous medieval love potion. What's that last little bit?
A blank bit of rolled up paper?

Nope, it's a super secret love note. Take the match on the back of the shrine and light a candle. Holding the paper to the flame reveals a secret message.

The actual note remains a secret and is safely tucked inside the shrine.
If you want to make your own super secret love note just use some lemon juice. When the juice dries you won't see a thing. Just be careful when using the candle... I burnt three notes trying to get a decent photo

Be careful kiddies!
