Sunshines, if you plant anything fast growing, it's likely to do the same as your conifers and refuse to stop at 6 feet! What you could do is to plant hedging and keep it pruned. Beech makes a lovely hedge, for example - either copper or green. It keeps its dead leaves on during the winter, too, and the new leaves are always a joy.

There are plenty of choices, but you'll have to be patient, I'm afraid. If you want 'instant', have you thought of a fence with a trellis on which you could train climbers?

hi spitzhenry the fence is a good idear many thanks
