mmmm my words of wisdom are these
prepare for loads of swearing, cut fingers and 4 or 5 attempts later!!! (myself not being a sewing expert) if you dont try then you wont succeed.
On the plus side once its made theres no stopping you from making more JUST IN CASE you need a spare.
What sort of hovercraft are you building? and what do you intend to use for skirt material?
