Well apologies, I didn't make it into the shop today as I was caught up unexpectedly with an occupational therapist who needed to assess my Dad when I was there. I've been cogitating the glass I've seen in the shop and the pictures on the website, and I think there is a real difference in quality. (Which is why I suspect the chap who has the shop probably imports unsigned seconds. I don't suppose the Studio may really consider him to be their representative.) I never really thought it was top quality stuff, hence the description of "large, colourful and cheerful" I should probably have added inexpensive.)
If you're asking the Studio to make pieces for you, you could ask for the spiral or spotty ones, if you wanted them. It probably would be cheaper than me getting them for you, and you may well end up with better made pieces. You can see the spiral goes a bit wonky on mine. I'm still happy with my pieces, and they did not cost a lot.
I like to fill all my empty spaces with glass, and there are some rooms, eg kitchen, bathroom, the spaces at the corners of the stairs, cloakroom etc. where you don't really want to put very valuable items in case of damage and if I can find cheerful things to put in these spaces, I'm happy.
