A few years ago my parents got me three colors of woven rug yarn to
replace the seats on lawn chairs. I lost the directions to replace the
seats on the lawnchairs and now have used the woven rug yarn to start a
crocheted rug but all I get is a single crochets thing resembling a
basket. My mother states that when she made them 40 years ago she recalls
having to place a marker along the single stitches and do something
different, but she can't remember the whole process. I would like to
purchase more of the woven rug yarn (wonder cord I think she called it)
and get complete directions for the process. I remember she made small
throw rugs for the bathrooms in our house.
If any can help me with any of my questions, I welcome your responses

I think the markers were probably to show where she had to increase.
If you crochet in a circle and don't increase every so often, you'll
get a tube (basket). To make a flat circle, you have to increase
six or seven stitches in every round. If you space them evenly, you
get a circle. If you cluster them in two locations opposite each other,
with a straight space between them, you get an oval.

"Wonder Cord" sounds like it ought to be a brand name for macrame cord.
Hobby departments might carry something like it. Also you could look
at rug yarn brands in places like JoAnne's.
