Firstly go through your old T-shirts or camisoles....
....and check the hemline of one that you want to use and see if it is suitable and not too worn out. Then with the hemline at the top, cut out a piece of your T-shirt or cami measuring 8 inches (20cm) across at the top, 7 inches (18cm) down, and approximately 5 inches (13cm) at the bottom edge. The following photo makes the top of the panel look crooked but it isn't really.
It is easier to see what to do with the white panel. This is an old one I made several years ago and it is still going strong. Once you have cut out your panel then zigzag around the edge. This isn't seen at all. Then cut two pieces of elastic approximately 2 1/4 inches (6cm). This will wrap around your bra strap so take this into consideration when cutting your elastic as you may want to make it longer if you have a wider strap.
Now, you will need some hook and loop Velcro. Cut two pieces approximately 3/4 inch (2cm), one piece for each side. Then separate one piece, lay the elastic 3/4 inch (2cm) from the top side edge then lay one piece of Velcro over it and sew both onto the knit fabric. It can get a bit tricky sewing Velcro depending on your sewing machine and you might have to sew it on by hand. Just make sure that the stitching won't come undone. Then add the corresponding piece of Velcro onto the other end of the elastic.
Repeat on the other side. That's it! Then you just have to insert the panel into your top, wrap the elastic around your bra strap and stick the two pieces of Velcro together. You might need to experiment a little to get the right length of elastic and Velcro to suit your bra strap as I mentioned before.
You could also add lace if you liked the look. This is a panel I bought quite a while ago but I didn't like the lace at the top so have never worn it. Instead of Velcro and elastic it attaches to the bra strap using suspenders (like we used to use to keep our stockings up when we were teenagers in the 1960s and before panty hose appeared in the shops). However, I didn't feel that they would stay done up so opted for the elastic and Velcro instead and have never had any problem with it coming undone.
So there you have it. A much cooler way to cover up instead of wearing two layers of clothes. These are quick and easy to make so do you think you will give it a try? Let me know what you think!
