To be honest, i got the idea for this label from a bishops finger bottle. Found a pic of the label on the internet and imported it into AutoCAD, the then traced over the outlines to get the label shape and flow then imported that into coreldraw where i added the txt and color. Pretty sure you can do it all in coreldraw, but i use AutoCAD daily so easier this way for me.
As for ideas of what to put on them, i like to see:
Beer Name
Brewery Name
Pouring Instructions (optional, but lets ppl know why there is sediment in there, alot of people won't know)
ABV
Units (optional, but i think it gives a good look
Volume (optional prob wont be accurate unless you measure will filling but again gives a good look)
