Here is a fairly quick and easy sewing project to try that is great to make for yourself or to give away. It is also a great way to keep your children's hair dry if you make it in fabric they like.
I would love to see a photo if you make a shower cap using my instructions. Please provide a link to this post if you wish to share these instructions with others.
Fabric (I use satin or lightweight cotton so it dries quickly)
Thin plastic (disposable tablecloths or plastic shower curtains are great for this)
Thread to match
Biro for marking on the plastic
Straight stitch sewing machine (yes you can even make this on a treadle!)
1) Make your pattern for the shower cap using fairly large paper. You need to cut a circle approximately 55cm in diameter. If you have really long hair or are likely to have rollers under it I would recommend 60-65cm. For children 50cm is usually sufficient.
2) Cut 1 piece in your chosen fabric and one piece in plastic for the waterproof lining
3) Pin around the very edge with wrong sides together. This keeps everything in place as you sew. Satin and plastic are very slippery when you are trying to sew the two together. Keep the pins right to the very edge so any pinholes created in the plastic will be hidden under the binding when you sew it on. Baste all the way around.
4) Open out the satin binding and sew it to the inside(plastic side) of the showercap as in the picture below. Fold over the end before you begin to stitch so you will have a neat finish.
5) Once you have stitched all the way around, fold the rest of the binding over the seam and over to the right side of the shower cap and stitch in place from the fabric side. This step covers the previous stitching lines. Sometimes I add lace at this step too.
6) With the plastic side facing up on the shower cap, measure and mark 5cm (2") in from the edge all the way around. This is where you will make casing for the elastic. Fold the end of the cotton binding over then sew the binding along the edge onto the line you marked earlier. DO NOT overlap or sew over the ends as you will be threading elastic through there shortly. Refer to pics below. Repeat sewing along the other edge of the binding to create two stitched lines. Tie off any loose threads.
7) Thread the elastic though the casing. I usually use a small safety pin or an elastic bodkin. Use enough elastic to make it comfortable and not too tight. Secure the ends of the elastic either by sewing or tying them in a knot. Hide the ends in the casing using a pair of tweezers to push them in. Decorate with the outside of your new shower cap with a satin bow or a fancy button if desired.
These showercaps can be washed by hand in lukewarm water or in a cold wash in the washing machine on a gentle cycle.
Here is a shower cap and a couple of make-up bags I made using a thrifted pillowcase that was made from Breast Cancer Awareness Fabric.
