Dave I wasn't being rude or having a go at you at all about the size of sheets you buy I was trying to be helpful be pointing out the bigger the sheets you can afford/ accommodate the cheaper it will be, as for matt or glossy one side I have never wanted or needed a gloss side in 50 years of using styrene sheets I cant see any advantage of it I love to hear from any one that has, not in modelling anyway.
Regards Howard.
