yep, I'd trim it down to give myself just enough room to seam it right up to the gold... then do the sashings from there.. Love the panel and ur assorted compliental fabrics!!
I rarely truely square anything... I eyeball it and "it's close enough"!... I"m so bad.... tsktsktsk.. I think I should be sent to my rooom ( sewing room, that is) to think about my bad behavoir of not really measureing and squareing.... .. hehehehehe
