Can I use a 3/4 violin

ruby

Sorry about the obscure title.
basically im looking to get a cheap violin for some slight 'tinkering'.
I'm not that bothered about sound or clarity so thats why Ive been looking on ebay and related sites, ive found that there are lots 3/4 violins on sale but only some 4/4.

so my question is, if i (a 4/4 violin player) buy a 3/4 violin and proceed to play it for a while, will it make much of a difference to my playing on the 4/4?
Will i struggle much?

I dont want to be concert player, i just want to carry a decent tune

What do you think


Sorry about the grammer, english isnt my first language
