I believe the blinds you have are the type that mount on brackets somewhere in the middle of the blinds (as opposed to either end). To release the blind from this type of bracket you should first raise the blind all the way. Next, you should see a piece of metal (tab like) at the bottom of the bracket. If you push this tab toward the window it should release the blind from the bracket. If it give you trouble, you may need to uease a screwdriver. For more blinds tips check out BlindFinder.com.
