Elann Esprit is almost exactly the same as Cascade Fixation bar the lower price, it's details are:
Fibre Content: 98.3% Cotton 1.7% Elastic
Made In: Brazil
Care: Hand Wash/ Dry Flat
Gauge: 25 st/4 inches 4.5 mm (US 7)
Yardage: 91m/ 100 yds (relaxed) - 170m/186 yds (stretched)
Size: 50g (1.75 oz) ball
Price: $2.75 USD
It's available in plain colours and prints.
Again the needle size is a bit big for socks I think, and it knits well on 3.25mm needles which is what most Fixation patterns call for.
Having used both the Esprit and the Fixation I really couldn't tell much, if any, difference between the two and the Esprit wears and washes as well as the Fixation does. If Elann didn't have such stupid shipping rates to England I'd be stocking up on the prints for sure!
