You make some very good points Howard. As you know, we have 5 hobby shops in our area of Durham Region and the eastern part of Toronto. I buy from all 5 as well as the internet shops, Ebay and yourself. What I can't get from the LHS I get from other sources. So, I think that I spread my cash around the hobby and support everyone, both brick and mortar stores and online ones.
You can also try to make a template of the area you need to foil with masking tape. I use the dollar store tape, as it's got a little less tack to it, and cut it slightly over sized. I then remove the tape template and apply it to the foil and cut out the shape I need.
