Well, as long as this thread is *bumped* again, I figured it's worthwhile to offer a direct link to the USCUTTER sales page for short-flute (landscape orientation -- wider than tall) blanks
https://uscutter.com/short-flute
and while we're at it, here's the link to the wire stakes --- https://uscutter.com/stepstake-2-wire-stake-for-4mm-corrugated-plastic-signs-case-of-50
Ur Welcome.
