Resource for simple wooden trellis plans

Does anybody know of a good online resource for trellis plans?  I want to make an upside down V shape one for a raised bed in my kitchen garden.  I saw some plans somewhere and now I can't find them again.  The one I saw was maybe 5' or 6' tall framed in wood and had sections of what they called lobster wire grids on each side.  It was joined together at the top somehow.  Anyway, I'd like to either do this myself or if I have to ask my woodworking husband I'd really like to have dimensions, materials lists, etc ready.

Thanks for your help!
