Cut your disposable decorating bag down to about 5 1/2" inches.
Squeeze the amount of glue you expect to use now. You can always add more. Remember from your school days "A little dab will do ya."
Clip the tip of the bag... really just the tip. You can always take more off if your stream is too thin.
You are ready to baste those seams away! This picture compares the glue bottle applicator verses the bag.
Once you are done with the glue bag wash it, let it dry upside down. This disposable bag is certainly reusable...just don't forget to wash before the glue dries.
After it forgetting to wash my bag for over a week, the glue was still usable.
Now I skip the wash, it's so easy!
