Our talented sewing expert Carolyn shows us how to create a stylish and unique cup cosy using Pintuck & Decorative-stitch Foot #46C to add decorative features. A cup cosy is an excellent way of giving hot drink cups extra grip, insulation and keeping your hands protected - as well as being eco-friendly as it will be reused every time you grab a cup of coffee to go unlike the cardboard sleeves! An elastic fastening gives the flexibility for use with a variety of cup sizes and the addition of pin tucks, which may be corded or uncorded, adds an attractive grip feature. Decorative stitches on your Bernina sewing machine are a great way to personalise the cosy and impress your friends and family!

Why use Bernina Pintuck & Decorative-stitch Foot #46C?

The Pintuck & Decorative-stitch Foot is designed to add widely spaced parallel pin tucks, sewn with a twin needle, followed by decorative stitching in between the pin tucks.  This technique may be used in a variety of craft/home décor projects as in the Cup Cosy and also in dressmaking.

Stage 1

Create a paper pattern for the cover. I used the one shown below; this was made by cutting open a cup from a coffee house, drawing around it and adding a half inch seam allowance. I have tried it on many sizes of cups and it seems to be a good fit.

Stage 2

Using the pattern cut out 2 pieces of fabric, 1 piece of wadding and 1 piece of stabiliser.

Stage 3

Place the wrong side of one piece of fabric on top of the stabiliser and sandwich a length of braided nylon cord between the two in the desired position for the pintuck.

Stage 4

Using presser foot #46C, a twin needle and straight stitch, sew a pin tuck by keeping the "ridge" of braided nylon cord underneath the centre of the presser foot, it should sit nicely under the centre groove. I used thread which matched the fabric however, you may choose to use contrasting threads to give added definition. Due to the shape of the fabric the pin tuck will be sewn in a gradual curve.

Stage 5

Continue to sew parallel pin tucks along the length of fabric by positioning the previous pin tuck under one of the grooves of the presser foot to achieve the desired spacing. I used the widest spacing.

Stage 6

The next step is to embellish the Cosy with decorative stitching; you may choose to embellish between each pin tuck, alternate ones or a selected few. Insert a single needle and place the piece of wadding underneath your fabric. I used contrasting threads and chose decorative stitches to personalise the cosy. I sewed the cosy on a Bernina 590 and used stitches 102, 104, 136, 168, 937, 2215 and 2216 in addition to lettering. If your machine has the triple stitch feature you will find that this gives greater definition to the stitching.

Stage 7

Attach a piece of elasticated braid to the centre of one of the side seams. Be sure that your stitch length is short enough so that the needle sews through the braid several times, you may need to reverse sew too. Cut off the excess braid.

Stage 8

Place the second piece of fabric right sides together onto the pin tucked and embellished piece, pin together and stitch with a half inch seam allowance. Leave an opening, for turning, in the side seam that does not have the elastic braid sewn.

Stage 9

Trim the corners and snip the seam allowance of the curved edges to facilitate smooth seams when turned.

Stage 10

Turn the Cosy inside out and ease the corners into shape.

Stage 11

Slip stitch or top stitch the opening used for turning and stitch on a button for fastening. Press well.
