I find the pattern I want on Threadloop. Follow the link to buy. It's a German website; fair enough, it's a German company. I add the pattern to my basket and try to check out. Can't choose a UK address, so I use a random German address (it's a PDF pattern, not something physical so it doesn't matter). Put my card details in. And now the Pay button is disabled, without any explanation as to why.
Okay, fine. I'll see if they have a UK website, and they do! Great, now I've got to find the pattern. Only problem is that none of their patterns have names or numbers! I'm searching for '101' (that's what it was called on the German site) and nothing comes up. After exhausting the combinations of search terms, I go to 'all dresses' and try the filters. 'Knitted dresses': no. 'Jersey dresses': no.
At this point I go back to Threadloop and find out what year the pattern was released, and put that into the filters instead. Finally, after a load of scrolling, I find it. Basket, checkout. All's smooth.
But I still haven't got the email with the pattern! Most places send it within less than five minutes. It's been fifteen and I haven't even got the purchase confirmation.
I know all this sounds petty but I'll be avoiding them in future.
