This flag mount is for 'mini' flags (w/ 8.5mm diameter 'poles') - I bought mine at Lowes, but I've seen the exact same ones at Wal-Mart. Each corner has a wire-nail-size hole (~1.5mm) for mounting, but you'll realistically only need two nails. I'll probably update it to make it more universal, but wanted to upload the first draft for anyone interested..
