Thank you for the replies - the trip will be in June 2018. Nothing is booked yet. Still refining the itinerary. I plan to book as much in advance as possible including rail tickets, etc. I am really just trying to narrow things down right now. Was planning train travel between Edinburgh and London but may opt for airline travel.
Was not planning to base myself in London - wanted to do 2 days there. Was actually thinking of basing myself out of Bath per Rick's suggestion in many of his guides.
I have several guidebooks (Rick Steves, Lonely Planet, Rough Guide) and have perused numerous websites. Have also spoken with friend and family who have traveled GB. The problem is that at some point, it's all just too much information. The options are infinite in their possibility.
I am aware that Liberty is not inexpensive - I have been buying their Tana Lawn fabric in the US for years at over $20/yard. One does not go to such a place because it is cheap but because it is an institution. One of my favorite knitting magazines - AmiRisu - has a great feature of a craft tour of London, so I was planning to follow that to see some of the spots of read about for ages like Loop London.
I think at this point, I just may amend the trip to spend 5 days in Bath or S-U-A with a foray into London for the aforementioned shops. London has much to offer and will likely require a return trip.
I appreciate the suggestions but some of the hostility that comes through is unnerving ("I hope you have a good map" "I don't know why you'd want to...." etc) Not much generosity of spirit on here is there?
