make seamless horizontaly

[Nikolai Vladychevski]

Hi,

Is there any way to run Map/Make Seamless filter only on horizontal
edges? (or vertical edges)
I am making a side bar for a homepage , so i don't need a complete
pattern, I only want horizontal edges to be seamless to use it as a
background for a table. But if I run Make Seamless filter it destroys my
design on the vertical edges. (gimp 1.1.24)

Thanks in advance
Nikolai
