Hollow Door upgrade! I’ve always wanted to try a DIY upgrade to hollow core doors, but the fact their material is so thin has held me back. Instead of adding vertical paneling whose extra thickness might interfere with the jamb, I just cut shallow grooves into the door carefully using my table saw. Now I have a plank style door like the designers for no extra cost! I just need help picking a paint color - ideas please!?#hollowcoredoor#diydoor#doorupgrade#diydoors#doorideas#interiordoors#interio...
