Thanks so much, Guys! I have found many charity shops. I actually have found some great ones here in Canterbury, where we are now. I even found a tiny one in East Finchley near London when I went to see Mark Kermode's favourite cinema.
Laura (rhubarbgirl) - I went to Portobello Road! It was very cool, but unfortunately the on;y good thing I found was a tiny old fashioned key. Other things seemed too pricey and they seemed to specialise more in antiques than clothing. Or else they were vintage and too pricey.
Karin L H - Thank you! Unfortunately by the time I got internet we were out of London and too late to check out this great suggestion.
approprio - Thank you for your help! I have been checking into every charity shop I come across. I hope to draw some of my finds and post them soon.
Love,
LR
