If you carry out a basic search, say - fabric - (just the one word) and press enter.
Then, on that new list of results, go to “Advanced Search” at top right.
It might, or might not, bring the word “fabric” over into the top box (keywords) - if not, just put in the one word again.
Then scroll down to just below halfway and, if you want to restrict the search to UK only, click on the circle against “UK Only”.
Then, just below that, there’s a section headed “Sellers”.
Click on the word “Include” and it gives the other option “Exclude”
Click on that and enter the sellers name in the box.
Then, down at the bottom, press “Search”
You’ll see towards the top of the new list of items “Save this Search” - click on that link and your basic search will then be saved.
For any search thereafter, all you need to do is to open that saved search each time (via your Saved Searches) and you can change the search words to anything you want and it’ll still exclude that seller.
You can add other sellers to that list - how many I do not know?
It’s a right faff to set up - but worth it when you get it working.
