P.S. I know you didn't mention what type of shop it was, but since it didn't ring a bell, I just assumed.
However, I do know some great shops full of handwork (a weakness of yours I know
) .
In this little shop here - 'Sé Sí' ('He She' in Irish) the workers make the clothes they sell in the shop while sitting on a chair/assisting etc.
In fact, one of the signs in the window says that if you make clothes, they will sell them for you in there. There's also a market (Cows' Lane market) where people sell some wonderful handmade clothes/accessories.
