Back in october 2017 (I was kinda active at this period, indeed), when I discovered an Insert concept that I called the « Tr-Insert ». It is basically 3 inserts inside the same barrel. Video just below :
How to make it ?
Your insert has to be ~2 times less wide than regular one (between 10 and 15mm wide). Roll the insert on itself and put them 3 at the same time inside the barrel. Depending of the paper you use, you have to use tape to avoid the insert got « unrolled » by itself before puting it inside the barrel.
I mostly recommand to do it with thin paper. I am not sure the 3 inserts can fit inside a barrel if you use thick paper (like if you do handmade insert)
This technique can be long and difficult for some of you, but I think we can do some funny things =)
I hope people can be interested more about the tr-insert and make their own !
thank you for reading, see you next time ! =)
