drawing chess positions on paper

I was wondering if anyone knew of an easy way to draw chess positions on paper. I don't have a travel/analysis set but sometimes I like to read chess books on the bus to work. Sometimes I don't think there are enough diagrams to follow along without a set - I try to get along anyway but eventually I get confused thinking of variations.

I obviously don't really want to draw every piece, so what I do right now is make an 8x8 board. To represent a piece I put the letter of the piece (K/Q/N etc) and the letter of the color (B/W) as its subscript. 

Still, this takes a while to do and I have only done it a few times because of how long it takes.

Anyone have any suggestions or whatnot?

print out a diagram from fritz etc..

Get rid of the B/W, use capitals for White, lower case for Black, like a FEN

If he had a PC he wouldn't be needing the diagram. He means handwritten to keep track of the position.

perhaps pick up one of these?

He can print out a diagram for every 5 or 10 moves of the game he's going to look at.

If visualizing is too much, and you don't want to use a set, you could always print out empty diagrams and pencil in the pieces.

That eliminates some of the hassle.

@goldendog and @rooperi - those are great solutions that I could combine together. i might do that.

also that little chess board looks neat. eventually i want a travel set and i'll look into that further.

My habit was to simply circle the blacks.

Using red ink for white stones is customary for recording games of go for centuries in Japan. If red ink is not available, it is customary to circle the whites.  

As long as you know the difference, it won't matter, which color is circled  or lower-cased.

I recently got a tablet (again), so I might improve this app by adding a larger text/picture window for book page scans/OCR.

Oh, the app does not include any tutorial packs since they were based on book (the screenshots with tutorial were used in our chess club, the actual tutorial PGNs were removed from the app prior to upload to google play store).

If there is interest, we can form a chess book club, where we'd all buy the same book and share tutorial packs based on the book.  I can update the app to message book club members so that we can discuss the book.
