Woodpeckers Baltic Birch Plywood, 3 mm 1/8 x 12 x 24 Inch Craft Wood, Box of 50 B/BB Grade Baltic Birch Sheets, Perfect for Laser, CNC Cutting and Wood Burning,

I just opened the box and half the order is completely warped. I know there’s always going to be some give with wood, but I don’t understand how half the order is fine and the other half is basically unusable. I’m going to try to flatten it and see if I can fix it but I don’t have high hopes. I don’t know how it cuts yet as I haven’t gotten that far yet.

Thank you !

Nice clean finish, but every board comes warped (not perfectly flat). Disappointing. Won't order again.

Many reviews question the thickness, surface, and warping, but they are what you should expect.Thickness : Baltic birch plywood is manufactured to metric standards, so it is 3mm thick, but is sold in the US as 1/8 inch thick because that's closest to the size we're familiar with. I don't think it's possible to buy 1/8 Baltic birch plywood.Surface: Baltic birch plywood is defined by a grading system. The pictures on Amazon showing knot free and blemish free surfaces are misleading. The grade of this plywood is supposed to have a certain amount of blemishes. The eight boards in my package showed fewer blemishes than I expected, so I was lucky this time. Baltic birch plywood is used for furniture in Europe but the 1/8th and 1/4 inch thick boards are too thin for furniture and are used where they won't show, like drawer bottoms and rear panels, so blemishes are expected. Those boards would probably be rated b/b. These boards are b/bb, with bb being the better side.Warping: the 1/8 and 1/4 inch panels are thin and are very likely to warp. I doubt if it's possible to make these panels so that they can't warp. If they came warped, or become warped before you use them, you can try dipping a sponge in hot water and wetting the concave side. Then put weights on it and let it dry in the sun. Do it again if necessary and you should get a flat board.I think the boards I received comply with the written descriptions of them. The photos of blemishes free boards are misleading, although most of my boards were blemish free or had very small ones. The quality was as expected and the price was good.

The wood performed as it should. I used it to make 16" hoops. The package was delivered in only a few days.
