Using a coupler is very useful, especially when you want to use the same icing with different piping tips. Or if you are simply fickle, like me. I tend to have the impromptu want to switch piping tips, so using a coupler is almost always a must for me.
|Step 1: Unscrew your coupler|
|Step 2: Insert the coupler into the piping bag and push it to the end, until you can't push any further. Make a mark at the point in the picture above. That's where you will cut it.|
|Step 4: Take the piping tip you want to use and hold it in place over the coupler.|
|Step 5: Attach the screw over the coupler tightly such that the tip does not move around.|
|Step 6: Done!|
As and when you want to change the tip in between whatever you are doing, just unscrew, take out the tip, attach the new tip you want to use and screw it back tightly to the coupler. Easy peasy! :)
