When did you place your order? I had a similar problem about 3 weeks ago. Placed an order for 2 lengths of finmeresco but didn't hear a word from them for 2 weeks. Called them. Turns out they actually cut the cloths the day i placed my order but all their emails to me to complete the order bounced, so they were waiting for me to contact them.
Bourbonbasted, I have a swatch of the 28429. From what I can tell, the colour is slightly darker than in the Merino brother pictures. The cloth has a slight sheen when viewed from a certain angle, but I am not sure how it will look when made up. The cloth feels pretty solid to me, has a bit of a nice thickness to it.
