one thing i'd have to say, looking at them now, is that you should pick out a font for your logo and establish a single one to be used on all your sauces. it's good for "brand consistency" if you have just one logo and people see it numerous times..it will stick in their heads.. then later it can catch their eye as opposed to several different logos which they may not recognize and possibly ignore. true..the duck is there which is consistent, i'd still say it would be a good idea for the logo itself to be the same. that way you can use it on shirts, business cards etc.
then again, you did say these were sort of a temp thing right?
