Actual dimensions will be very close to the listed 20\" × 30\" size.\u003c\/p\u003e\u003cp\u003eThin Baltic Birch can develop some bow or warp, and larger sheets are more likely to show it. We do our best to ship flat, usable material, but hold-down pins, magnets, or other work-holding methods may be helpful during cutting.\u003c\/p\u003e\u003cp\u003eBecause the clear finish is already applied, masking is often unnecessary. Light laser residue can often be removed gently with a baby wipe or soft lint-free cloth. Wipe carefully to avoid damaging the finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLaser Settings\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGlowforge:\u003c\/strong\u003e Medium Basswood Plywood \/ Proofgrade-style settings can be used as a starting point.
