Hey Emma,
welcome on the forum; for one flag it is always cheaper to just go to a copy shop or low-key printer and have one made, you can even print one yourself on special printing paper and iron it on a blank flag!
Just make sure the flag is:
- not too heavy!
- Not too big, both spread out as well as packed, so use thin fabric that does not get wet when snowed or rained upon (no cotton etc)!
- a bit durable, though weight is more important.
Send us the pics!

Cheers,
Harry
