The needle goes down (to the wrong
side) at A. Leave a length of thread (one to
two inches or more) under your thumb on the right side.
Bring the needle up at B and
down at C, making a back stitch. Continue to
hold the tail in place.
Bring the needle up again at A.
Make another loop the same length as the original
free thread, going down at D.
Bring the needle up at E and down
at B, creating the second back stitch. These back
stitches lock the loops in place. Notice that when doing the loop
stitch, the thread is toward you, and when doing the back stitch,
the thread is away from you. This further creates a locking stitch,
helping to hold the loops the same size.
Continue in this manner until the area is filled
(usually in straight rows). Cut the pile and brush out for a
very fluffy appearance, or leave the loops intact (such as for
A trick when requiring loops of
even lengths is to use a fat knitting needle, a free finger,
or other object (stiff cardboard cut to desired size) which will
keep the loops the same size as you work.
