ideas christmas presents mum

Christmas gift for Mom?
My mother is 49 and I give him something good for Christmas, she appricate. Me (15) and my sister less than (13) is going to put our money together so our price range is around £ 30-ish. Ideas?
I've got my mom a pair of pearl earrings silver in the form of potato and they only cost £ 15. Some things in smaller stores jewelry is cheaper than you expect and can be quite unusual.
Play him off, keyboard cat.
