got my first sewing lessons today

justs lets say i would defo fuck up the banner but fear not i've roped in the experts to a banner there will be no probs sticking a hoops flag together but i need to know sizes and shit.
Secondly when it comes to sticking a design on it things get more complicated so best we keep it as simple as possible.
i'm thinking big hooped flag, celtic crest in the middle and talkceltic.net on it and thats it and of course a big star.
any other suggestions start talking now cos i need a concrete design to work on and then there's no going back.
