What I would do being you don't have dry stickers and want to use the poplar is--------I would cut my stickers first then stack them very open------------meaning, start the stack a foot or 2 off the dirt if possible then several inches apart, then turn the next layer across these still leaving several inches between each sticker from side to side, keep building layers, put a little weight and a waterproof top on them and let them dry for as many days as possible before you use them, if you have electricity, probably using a fan to force some air through the stack will help. If you saw your boards the same day leave them stacked on top of each other for 2 or 3 days then air stack them using the stickers-------in my opinion this way would be better than sticker stacking them the time they are cut. What I do is grab a few air dried boards that I sawed a few months ago usually 12 ft then saw then into 1" strips-----------I stack all these strips together with level ends---------I then wrap 3 bungee cords around this stack them measure 4ft(the length I use)-------------I then use the chainsaw to cut through the stack-----------the bungee cord is spaced so when I saw through the stack--------each 4ft section is held together-----------Then I can pick up the whole bundle at the time---------Works for me. Keep in mind I am mainly cutting pine framing material so I don't plane my stickers, but I am VERY careful about looking for stickers that are not cut very close to what they should be. If I was cutting High Grade Boards------if I didn't have any-----I would go buy some dried, Planed boards to cut my stickers out of. Good Luck!! Randy
