Decisions, decisions.

Last year, I was very honoured that Debbie from Skein Queen offered to dye yarn to accompany her recommendation of The Sewing Machine in her yarn club. 
Debbie's yarn clubs are legendary. Sign-ups vanish quickly from the website and I think there is often a waiting list. Each parcel is book-themed and accompanied by the literary equivalent of Tasting Notes for the book.

Debbie sent out two skeins of yarn to go with her Tasting Notes. 

Clydebank, to me, has an industrial feel. It's a mixture of metal and oil and sooty speckles.

Glasgow Sandstone is a semisolid glazed yarn, with all the warmth of a tenement on a sunny day. 

Interestingly, in combination, they resemble a yarn I dyed a long time ago called Tenement (I will dig through my files and see if I can find a photo).

These yarns have been sitting safely in my stash, waiting for the right moment, and I've decided it's time they became socks. The base yarn is a blend of 75% Bluefaced Leicester and 25% nylon. The BFL sheep produces a curly, long-stapled, lustrous, wool which is great for socks and smooth to knit with. It was my favourite fibre to dye when I was running The Yarn Yard because it took colour so well.

My question though, is which one shall I knit with first? I think I have a favourite, but since I intend to knit both, I'm going to let you decide. 
Let me know in the comments and I will cast on this week.
