Yep, permanent marker is another method that works. Colour in the area to anneal and the ink burns off at approx the right temp justs like acetylene soot. Soap/candles work like a match/lolly stick and char/leave a dark mark at around the right temp

Connor, a 2 x 1 metre sheet of 1.5mm 1050-h14 is ~ £25 - 30 + VAT (prices move up and down a little regularly) from a proper aluminium stockholder so much cheaper overall than buying small pieces from Frost etc. If you don't have the means to transport something that size then http://www.aluminiumwarehouse.co.uk/ have a cut to size service which is still an expensive way of buying but appears to a bit cheaper than Frost although that'd depend on carriage. More importantly you aren't limited to 600 x 900mm

As said 1050-h14 can be stretched/shrunk a bunch before needing to anneal but it if you're new to metalshaping then it's worth annealing any areas that'll be worked a lot as it makes life easier/faster overall- annealed 1050 is like butter to work.

1050-h14 is 99.5% commercially pure aluminium which is cold worked to 'half hard'
1xxx is commercially pure ally (googling aluminium alloy grades will get a complete list for 2xxx, 3xxx series etc and more indepth stuff)
H-14 is the temper description, explained in more depth here http://aluminium.matter.org.uk/aluselect/tempers.htm
3003 aluminium doesn't exist in the UK, we have 3103 which is effectively the same thing but it's less commonly stocked and when it is generally only in 2500 x 1250mm
