I have a total of 139 flags and they are 4x6in 5x8in 12x18in 3x5ft and 4x6ft . Why do you choose to collect a lot of Canadian providences? Do you live in Canada?
I know I'm 4 years late but: Personally, as a small flag collector, I like the small versions. They're cheaper, and they don't need much space. You can just stack them on top of each other, or place them all in a mug, container, etc. I like big flags, but it's a bit of a hassle when you can't find space for them. So I collect the small, handheld ones, although they're harder to find.
