What you need:
½ yard/40cm of 54"/137cm wide curtain fabric (wash before using)
¼ yard/20cm bump* or curtain interlining
*There are a few things you can use to keep the heat from burning your fingers. I've tried a lot of options and have found that the polyester bump that my local curtain fabric shop sells is by far the best for oven gloves. There are insulated wadding/batting fabrics available but not in my town - another reason for me to use the bump - but, if you can get your hands on some, by all means use it. You can use also towelling but it takes a long time to dry and is quite bulky in the seams.
I devised a test to check my bump for heat resistance: if I can hold the oven glove (with my hand in it) on the sole plate of my iron for 10 seconds without the heat getting unbearable, then I reckon I'll be able to get the tray of biscuits or cakes out of the oven and on to a cake rack before I burn myself. Please note, if you try this yourself, BE VERY CAREFUL!!!!
How to draw the pattern:
1. Draw an 8" vertical line, XY, down the middle of your paper.
2. Mark the centre of that line and call it Z.
3. Draw a 7" horizontal line, VW, centred on Z ie 3½" each side of Z.
4. Draw 4" vertical lines down from both V and W to S and T respectively.
5. Join S to T.
6. Draw a 2" horizontal line, QR, centred on X.
7. Draw a curve freehand from V to Q. Don't draw the other curve - see next step.
8. Fold your paper along your XY line and cut out the shape. Because you're cutting the curve on the fold, both sides will turn out the same.
The first drawing was drawn to scale but I don't know if it is now after being scanned and re-scaled in Photoshop!
This is piece B. To make piece A, extend from the SYT line by 8".
You should now have 2 pattern pieces like these: (Note that the 7" line on both is on a fold.)
To make the cutting process easier, cut out one more paper pattern for each of A and B so you now have 2 of each.
Cut 2 x A on fold of fabric
Cut 2 x B on fold of fabric
Cut 4 x B on fold of bump
This drawing is definitely not to scale! :oD
Making them up:
Mark the foldline of the bump pieces with a marker pen or by pressing with your iron. Pin bump to the wrong side of one of the A pieces matching the curved ends.
Stitch down your marked foldline. Fold bump back on itself so you now have a 4 layer thickness.
With wrong sides together, press both B fabric pieces along foldlines. Pin B pieces to the right side of the other A piece matching the curved ends.
Fold the ribbon in half and pin the raw edges to the middle of one of the straight edges of the A piece. Sew ribbon to A using a ½" seam. If you're attaching a label to your oven gloves, do it now.
(I don't have photos of the next bit but I hope it makes sense!)
Pin A pieces with right sides together enclosing the bump and B pieces in the sandwich. Leaving a gap of about 4" along the straight edge without the hanger for turning, stitch using a 5/8" making sure to catch in all your layers. Stitch *slowly* around the curves. If you have a walking foot, use it. It does make sewing all the layers much easier.
Trim seam to about ¼" and clip curves.
Turn through the gap pushing your hands into the ends to push out the seams. Slip stitch the gap closed.
And here they are in use - or showing how they would be used if I'd cooked invisible muffins! :oD
