Optimal ratio of linen to cotton for summer shirting, w/r/t wrinkling?

[Andrew Ryan]

Title says it all. I'm only experienced with pure linen, whose wrinkles I can't abide for shirting fabrics, and 70% cotton / 30% linen, which does just fine - light and airy, just enough texture and still presses up nice. That said, having a hard time finding that ratio - seeing more and more on the 60% linen / 40% cotton and higher (in linen content), which gives me pause before having a shirt made up without seeing how the fabric would perform.

Any experiences anyone cares to share? For what it's worth, lightweight cotton does just fine in terms of heat in my climate - it's the beautiful texture that I'm after, and I'm already well-stocked on chambrays and end-on-ends.
