Separating a section of a graphic
I've found a vector that I would like to use as border (i.e. be able to have it turn round corners).

In order to do this I need to separate a section of it (otherwise the border function will have to create this whole strip before it can turn). I've tried to ungroup the elements and use scissors and knife and use the direct selection tool to try and isolate a smaller section of the design - but it always seems to select an unwanted section of the vector (the black part) - and when I try and drag it away it goes all funky. Can anyone suggest a way to cleanly isolate a minimal section of this pattern?
