Details with pictures for applying RIC-RAC
First you must decide how wide to cut the
bias. I always make a test piece to wrap around the fabric and
batting that I've used in my quilt. For this application I
usually want my binding to show a little bit more and so cut it wider
than I usually use.
Try starting with a 3" wide bias strip
and see if you like the look.
Measure your ric-rac. In my example it
is 1/2" wide.
Find the center of your bias: 3"
divided by 2 = 1-1/2 inches
Mark a line where the edge of the ric-rac,
when stitched down the center, to the center of the bias, will
hit. In my example: center of bias = 1-1/2" minus half of
ric-rac = 1/4", so I draw a line 1-1/4" from the edge of the
bias. I find this actually saves time over just
"eye-balling". The curves in the ric-rac can be very
distracting when trying to sew a straight line!
