Okay, either I'm going crazy and I've pushed the "discard" button instead of "send" twice this morning or the system is playing up today (I suspect it may be the former - I'm not at my finest this very moment).
I washed a staple of the fleece last night and it's so beautiful. The clean really brought out the luster so I'm pretty confident in calling this Leicester I think.
I haven't heard back from the seller yet but I'm pretty sure I'm not returning the fleece - it isn't what I thought I was buying but it's still a good bargin ($5 for over a kilo). Not that I intend to tell them how pleased I am with it - they sold something under an inaccurate description.
Thanks for all you advice.
