January and February should see you putting into practice the many re-arrangements and alterations that you have long since decided upon, though you have put off the actual doing of these things from time to time, for one excuse or another.
If you know of any particular accessory or fixture that would have helped you to turn out more work - better work - and more conveniently during the recent race against time, now's the time to install that accessory or fixture. If you wait, you'll very likely be in the same old state of turmoil next December.
If you have never taken a thorough inventory, do it this month, for there is nothing like a good inventory to show just how strong or how weak one is.
Apparatus and supplies may have a value to you many times more than the market value - the price you would be willing to pay, were you considering the purchase of similar articles from another photographer. Be fair to yourself, and do not deceive yourself by compiling too favorable an inventory. No one else may ever see the list and the figures, but that's the very reason why you should have a genuine inventory.
Nothing is more unsightly to a careful workman than a print made with a mask that is not perfectly true. It is a simple matter to cut a mask - and again it isn't. It's a rainy day job because it requires time, care and patience. And when you have a nice set of masks cut you are sure to find need for an odd size just when you don't like to spare the time to cut it.
This is where Eastman Mask Charts come in handy, and once you have used them you will always have them on hand. The charts are simply pieces of masking paper ruled for every size of mask you may have occasion to use. These horizontal and vertical lines are one-quarter of an inch apart and are numbered in inches both ways from the center and along the four sides.

It is a simple matter to follow these lines with a sharp knife and cut a mask of any size with absolute accuracy, for the difficulty in making masks is not in the cutting but in laying out the size and being sure of securing a perfectly true opening.
Mask Charts furnish the draughtsmanship, you furnish the labor. The price is 10 cents per dozen for 5 x 7, 15 cents per dozen for 8 x 10, and 30 cents per dozen for 11 x 14, at your dealers'.
