I've got four shaker style wardrobe doors to make for my daughter, originally I was going to make the styles and top, bottom and middle rails with 25mm MDF, route a 6mm groove to fit two panels of MDF, but I'm thinking this may make the doors heavy, so instead I'm propose to make the the styles and rails with soft wood, routing a groove to accept 6mm MDF. The doors are 1670mm x 450mm, they are to replace some very shabby doors, would the softwood option be best?
Thanks.
