in the unconscious state of mind, you can pull yourself out and throw out two rhymes and work it back. You get the rhymes first and work it back and then see if you can make it make sense in another kind of way. You can still stay in the unconscious frame of mind to pull it off, which is the state of mind you have to be in anyway. –– R. Zimmerman

An Example Tube Use
150mm lens
With standard helix, you should be able to focus to approximately 1.4 meters.Without any extension tube, you can just fill frame with a square object that measures approximately 15 inches to a side.
The 8mm extension tube lets you fill the frame with objects between 11 and 40 inches.
The 16mm extension tube lets you fill the frame with objects between 8.6 and 20 inches.
The 21mm extension tube (which is no longer made) lets you fill the frame with objects between 7.6 and 15 inches.
The 32mm extension tube lets you fill the frame with objects between 6 and 10 inches.
The 56mm extension tube lets you fill the frame with objects between 4.1 and 5.7 inches.
What's In That Bag..
Lens Wraps protect, but they also hide.
when you have just one item it is easy to remember what lies behind the blue wrapping. However, when your back is full, labeling or tagging those things is a better idea. If you label by writing on the lens-wrap, you have to keep it separate and sorted. I prefer to have movable labels.
This cryptic note lets me know that a Hasselblad A-12 back is loaded with IR(infrared) film and ready to use.
These tags are just “male” velcro so they a tenacious but temporary stickers on the “wrap.” It is easy to move them to another wrap. The hardest part is finding the velcro.
