Create a flipbook printout with iStopMotion. It is important that you end up with about 100 pictures, maybe a maximum of 200. Any more and it becomes difficult to flip through them. You can set the printing in iStopMotion so that it prints out only every other (or 3rd or 4th and so on) frame depending on how fast your animation is.
The size setting in the print dialog (Choose File -> Print Flipbook and switch to the iStopMotion panel using the third popup) does refer to the size of the flip book, not the paper (which you set in the Page Setup dialog). You might want to try about 5 to 6 cm (or about 2 inch) width and 3 to 4 cm (or about 1.5 inch) height.
Cut our the images and create a stack. The first image goes to the bottom of the stack because you flip the book from back to front.
Take the stack and dip it on the table with the "flipping" edge to align the paper and create a clean edge. This is very important so that you can flip the pages easily.
Take a vise and firmly hold the pages together with it. Fix the vise so that the back of the book can easily be flipped through. This is important so that you can get the glue between the pages easily.
Glue the pages together with liquid glue suitable for paper at the back edge. Make sure that you get glue in between the pages so that they stick together firmly.
Glue a strip of cardboard to the back of the flipbook as shown in the picture. This will serve as the cover.
Now let the glue dry properly. This may take some time depending on the glue you use. When the glue is dry, you can fold the cardboard and cut it off where it sticks out from the pages.
Enjoy flipping through your animation!
