I also think Applespider's suggestion about creating a non foodie destination market near the pools on Dartmouth road could be the answer.
Especially if its a decent mix of vintage and craft, though to be honest (and here I will probably be making myself unpopular) too often craft stalls alone are full of twee overpriced useless 'stuff'
what we DONT want to do is set up stall based competition to our excellent craft shops Doopoo, and Stag and Bow.OR our vintage shops Montage and Dapper.
The more I think about it therefore, the more I veer towards the idea of having more clothing based vintage on dartmouth road, and maybe some recycled/restyled clothing and home ware stalls.
