Ok yeah I think I'll do a combination of both: cut grooves into the side edges to slot onto supports and then drill holes for rods going into the back. Thanks for your help guys!
Yeah I might be talking about hidden brackets haha I dont know I just dont want to be able to see any fixings when the shelves are up! I dont know how I'd be able to support at the end as if the wood fits the length of the alcove, theres no space to slot it onto side brackets?
So I'm completely new to DIY, house decorating etc. but I thought I'd be adventurous and try out floating shelves with a couple of planks of old scaffolding I have.
Turns out its actually more complicated than I thought and I'm finding it hard to find advice specifically on what I'm trying to...
