The ch4 extended sc would simply make a taller bar on the sc stitch and would not produce loops. What is the pattern for the next row/round? If the next row is multiple stitches in each sc (and not loop space) then the added height of the bar alows the row to bend for the ruffle. Is there a photo with the pattern showing the ruffle?
Happy New Year!

you did a great job ...
some patterns do NOT include the comma so that you will understand that : YOU: chain 4 then sc in same stitch, across.
In other words its all in the same stitch across or around that row or round... OK??
otherwise most would be skippin a stitch an that is what they did not want you to do ... OK??
and you can make it more pronounced by doing a ch 5 if you want too...
