I should be an interior designer

This afternoon saw a trip into B&Q after College, to look at flooring, skirting board and wallpaper for my installation.

Having measured my floor space to approx 6m2, I initially looked at carpet tiles- NB: I need a flooring that is thin; there is a fire door in my area and therefore as the door would be opening and closing, I need something with a tread of <5mm (the space left under the door) - the tiles worked out at just over £60 for 6m2.. Now whilst I want a quality fit and aesthetic, I'm a student and realistically I really don't have that sort of money to spend.
The next idea was vinyl, again expensive. My total floor area is 1.5m x 3m, and the vinyl flooring came in rolls of 2m x 2m, at £25 each. Firstly it would come to a total of £50, but I would also have a rather unsightly join in the middle of my flooring. Not nice.
The third option, Fablon. This is a product that is basically sticky back plastic with the look of a vinyl wooden floor. Now at £9.99 per roll, that's pretty nifty. Apart from when the roll comes in 1.5m x 0.9m, which then means I have to buy 4 at the grand total of just under £40.. Not so nifty.
I'm not a tight wad, but at the same time I refuse to pay £40+ just for a floor that's only going to be stuck down for 3 weeks then binned.
But alas, a miracle was cast upon us! Mumma Wright came across a dark brown carpet (the type you'd see in a classroom, but hey I can't afford to be choosy) that was about 4mm thick, and the best part? £3 per square metre!!!! £3 x 6m2 = £18, thank you veeeery much and I'll take that nicely.
The wallpaper choosing was a million times easier. Now I'm not saying that I should be an interior designer... But I should. I was going for a generic 'hallway' type wallpaper, but also had the key point in mind that a brightly coloured/ patterned design would just flush my hanging photographs away, their intention and intensity would be lost into the background of a wallpaper style.
