Kids beads (Southampton SO16)

Hiya I have been doing a big Halloween display/goodie bags for the last couple of years. I'm looking for some kids pony/plastic and letter beads or even possibly wooden beads to make bracelets for the goodie bags like one shown in the picture from last year. I plan on either adding quotes like trick, treat. Boo ect. Or I'll be getting some small halloween beads/charms for the ones without letters :) any help appreciated! Thank you for reading! Can collect :) (my brother lives around the new forest so may also be able to collect from there
