Do you have a place in your linen cupboard where all the neglected old pillowcases live? I'm so glad to have repurposed at least one of mine - here's the pillowcase apron.
And here's side B:
Here's how to do it:
You will need:
ruler and pencil (or washable fabric marker)
(I used a housewife pillowcase with a folded-over section - if yours doesn't have this you will also need some ribbon or other fabric for the ties and neckband).
Turn your pillow case inside out, and carefully cut away the folded-over rectangle of fabric at the open end.
First: the neck-band and apron strings
(it's good to get the fiddly bits done at the start)
On the cut-out rectangle of fabric, mark three 4cm wide strips, starting at the long hemmed edge.
The strip which already has one hemmed edge is going to be the neck band.
Fold and press a 1cm hem on the other long side, then fold and press again to form a double hem.
Stitch along the folded edge.
The two strips without hems will be the waist ties.
Fold and press a 1cm hem on one short end of each.
The press both in half lengthways, fold in the long raw edges to the centre and press again.
Fold again lengthways to enclose the raw edges, and topstitch along the open edge to form the ties.
(They will still be unfinished on one end - this is where they will attach to the apron later).
This is what they should look like now:
Now for the body of the apron:
Fold the pillow case in half lengthways.
Mark a point 11cm from the fold on one of the short edges - this will be the top of the apron.
Mark another point 28cm from the top edge on the side-seams of the pillowcase.
Join these two pints with a smooth curve - this is the stitching line.
Draw a cutting line 1cm outside the stitching line and cut along this through all four layers of fabric.
Cut off the top seam 1cm from the edge.
It should look like this now:
Now it's starting to look apron-shaped....
Attaching the ties and neck-band
Fold back the upper layer of fabric to separate the top halves of the apron - now you are looking at the right sides of the fabric on the inside of the pillowcase.
Pin the neck band in place, aligning its raw edges with the top of the apron.
(The neck band needs to be placed 1cm in from the sides to allow a seam allowance when the two layers are joined together - as in the photo above).
Baste neck band to apron and pin to make sure it doesn't get caught in the seam allowances later on.
Pin the waist ties in place with their raw edges against the side seams 1cm below the point where the curved edge meets the straight side seams
(again, this is so they don't get caught in the seam allowances).
Now to stitch it all together:
Pin the two layers together, sandwiching the waist ties and neck-band inside the pillowcase, between the right sides of the fabric.
Stitch all the way around the edges of the body of the apron, leaving a 10cm gap in the lower edge for turning.
Leave a 1cm seam allowance all the way around - even on the side seams which are already stitched. You need to sew inside the original seams in order to catch the waist ties in the new seam allowance.
When you come to sew over the waist ties and the neck-band, backstitch and sew over them again to secure them really well.
Trim the corners and clip the curves to help it all lie flat when turned.
Turn through the gap in the lower edge, and press very well all the way around - it's worth doing this from both sides if you're wanting the apron to be reversible.
Press the lower edges under by 1cm at the turning gap, and pin this closed.
Now topstitch all the way around the body of the apron.
Hurrah! All done...
