Small gift ideas

[Bridge9484]

I've bought my parents tickets to a show for Christmas but I'd like to buy them a little something to go with the tickets and I have no ideas! Ideally a joint gift under £15. Help please

Maybe a voucher for coffee and cake somewhere near the show?

A home made hamper ie card box covered with lovely paper rather than buying a basket, full of all their favourite edible luxuries?

What show? Just so we can suggest if there is a theme?
