These are the instructions for making a HBPocket. Made from the Honeyboy pattern.

This is my big roll of pattern tracing paper. It’s a roll of
printing press paper. I think it’s by HP. It works so
great and was pretty cheap for hundreds of yards.
Onto the instructions…..
Trace your HB Home pattern in the size you want. Cut
it out. Lay it on another piece of paper and trace it
again with a 1/4″ seam allowance all the way around.
Now take that pattern and lay it on another piece of
paper and trace around again. Only this time laying a
ruler between the elastic markings on the legs and
draw a straight line from mark to mark. Round and
soften the mark where the regular pattern meets the
extending line.
Now you have 2 pattern pieces for cutting out your
fabric. The big leg one is for the outer WP layer and
the smaller leg one is for the inner Micro layer.
Now fold your WP fleece and lay the patterns straight
edge on the fold line. Cut around the pattern. Do the
same for the micro layer using the other pattern.
Now you have both your fabric pieces cut out. Lay
them right sides together.
Transfer all markings onto the wrong side of the WP
layer with tailors chalk. On my lines I also mark a little
big past the elastic size I’m using.
On the RIGHT side of the WP layer mark where the
tab goes.
Place your tab in and pin on both sides to keep it in
Pin all the way around lining up all raw edges except
the front area. Sew on your Aplix, then pin the rest.
The WP layer will be baggy. Starting at the back on
the elastic line, sew around diaper with a 1/4″ seam
Ugh, blurry picture!! As your sewing with your 1/4″
allowance you come to the spot where you are going
to tack on your elastic. If your using 3/8″ elastic you
need the seam bigger than 1/4″. So jog in slightly
towards the top of the T and jog back to the edge
after you pass it.  Or when you trace your pattern in
the beginning you can trace with a 1/2″ seam
allowance.  I don’t like that so I stick with 1/4″
After your done sewing the diaper together, tack the
elastic on the chalk lines you have marked. Pull the
elastic tight and tack on the other mark. Do the same
for the other side.
Here’s a picture of the WP side of the diaper before
it’s turned with the elastic sewn to the legs.
Now it’s time to sew the elastic onto the opening in
the back. I use 1/4″ elastic. Tack the elastic onto just
the WP layer on the elastic line or as close as you
can get to it without sewing through the micro layer.
Leave about 1/8″ WP sticking up top of the elastic.
Do the same for the micro layer. Here’s a picture of
the elastic sewn to the WP layer and the micro layer
before it’s turned.
Stick the free arm of your sewing machine inside the
pocket opening. Fold the raw edge of the opening
over the elastic and straight stitch all the way across
being “very” careful not to sew through the elastic.
Here’s what the pocket looks like before the diaper is
After you turn the diaper, sew a straight stitch through
the 2 layers at the very edge of the opening…right
where the elastic is tacked on.
Here’s a blurry close-up to show you what I mean
Here’s the pocket opening after the diaper is turned
and the ends are tacked.
Here’s a little trick I do even on regular HB Homes.
Before you start your topstitching, pin the layers
together in the middle making sure the layers are
even…the same amount of WP on each side.
I don’t know if you can make this out or not, but when
you are topstitching jut into the diaper at the elastic.
Continue to topstitch in the microfleece layer until you
reach the folded over WP layer.
Here you will want to stitch in the ditch all the way
down until you get to the microfleece again and then
after the elastic, jut back out to your 1/4″ topstitching.
Make sure your elastic is inside the fold over WP
Here’s what the inside looks like after it’s been
Here’s the outside view of the unstuffed HBPocket. I’m
not too happy with my tabs. I should have done two
trains instead of words on one side. Don’t like it!
Serge together a big square of your two soaker
materials. I use nantucket or burley terry and a layer
of thin twill.
Fold into 3rds and stuff inside the diaper. I put the
seam side towards the front so baby can’t feel it.
Here’s the finished product all stuffed!
