I printed these bag holders for myself and used them and let me tell you ... game changer. I used the large size to fill my 10" piping bags. But the best part was using all three size to hold my bags of flood after I cut them! Add a piper clip on the end and no mess at all!
The small size works for 8" bags and large for 10" bags. But I love the medium size to hold my bag of flood.
This concept was not my idea but this is my version! I do not know where the idea originated.
