Simple plastic bag holder

Step 2 Drill the holes

Then I drilled 3 holes in each large piece, the diameter of the holes being the diameter of the small pieces (0.9 cm in my case). Notice that the middle hole is perpendicular to the end holes. I drilled all through the pieces of trunnion. Be sure to make one and only one middle hole a little bit larger (with a file, for instance), because you will use it when adjusting the holder to the size of a bag.
