CAT 6 spool for home use in the UK

I'm in the UK, and about the set up my office at home. I have an RJ45 wall outlet in the room that I'm going to connect everything from. I'll be connecting a few devices (5-10) so to keep things neat I want to make my own CAT6 patch cables.

What cable should I be using? I remember reading somewhere I don't a solid spine for patch cables, but where can I buy a spool of this? Ideally it would be white, but I can live with other colours. I don't need loads, but if I have to buy 100m I will.

Where would you get this from in the UK? What brand? Any help is welcome! thanks :)
