nose concave clarification

I have exhaustively looked through the archives, and found much good information. I think a shallow(1/4"), blended, short(24")concave will do good on my 9’6 performer template, 7" square tail. What is the easiest way to do this? Tape off around the outline, then take down the stringer, and lightly sand to feather and blend in. Any other suggestions or comments? Thanks- gill
