getting shelves up- PLEASE help!!

[jessicat25]

hiya,
we have been trying to put a set of 4 shelves up in our bedroom and my partner has gone and put up all the brackets. unfortunately he did not really think about actually attaching the shelves to the brackets!!!
so does anyone have any ideas of what to do? the shelves do not have any holes on them and the brackets are thick chucky wood ones. we were wondering if we got very long screws and drilled them through the shelves into the brackets?? would that work??? the shelves will be used for either storing clothes or books, so they need to be quite strong I think.
any advice is more that welcomed!! so confused!
thank you

Shelves don't usually need a lot to hold them down on their brackets unless they overhang the front of the brackets too far - gravity usually does most of the work, so bit of adhesive or a panel pin or two is usually enough just to stop them sliding sideways.

If there is a large overhang at the front, then some more substantial fixings near the backs of the shelves would be in order to stop them tilting.

If he shelves are above head hight a screw thru the top down into bracket should do and not be visible.
