What is a Pastry Bag?
The pastry bag or cake decorating bag is the cone shaped bag used to
decorate a cake. A pastry tip is connected to the end of the bag using
a coupler. The bag is then filled with icing and used to make the
decorations on the cake.
Which type of bag do I need?
There are two types of bags I use on a regular basis.
- Reusable Decorating Bags
- Disposable Decorating Bags
Reusable Cake Decorating Bags


Reusable bags are bags that can be used, washed, and used again.
I recommend using these bags for most of your cake decorating. A good
quality bag will last you a long time.
The best sizes to use when decorating cakes are the 10" & 12" bags.
An 8" is a little too small and anything larger than a 12" becomes a
little awkward to work with.
Never put your reusable bags in the dishwasher. This can break down the
fibers in the bag and cause it to rip or tear easily. Always wash your
bags by hands with warm, soapy water.
When you purchase a new decorating bag, it is not ready to decorate
with yet. You will need to
prepare
your pastry bag
first.
Wilton has just come out with this
great decorating bag holder. Looks like
a great way to organize your decorating bags while your cake decorating.

Disposable Pastry Bags

Disposable cake decorating bags are plastic bags that you simply use
one time,
then throw away.
These types of bags work good in situations where you are using a lot
of colors.
Disposable bags are usually purchased in packs of 12, 50, or 100. I
usually pick up a pack to have around in case i need it. However, if
you are new to decorating or don't decorate a lot, you can just choose
one or the other for now. You do not necessarily need both.

filling
and holding decorating bags.
