This is a great tip! Thank you so much for sharing.
To do color striping, instead of doing two different wraps and putting them in the same bag, could you just layer or place the different colors side by side in the same wrap? This could also work great for painting stripes on the plastic wrap and filling with white icing so that you don't have to get icing in your color from double dipping like you do when you fill the bag directly.
