I decided to sew these up while I was waiting for the fabric to make the retro-bombshell dress following Gretchen's online course - just look at all those curved seams!
Now I don't know why I waited so long! They were quick and easy to make and are so useful, I have used them a lot already and can't believe I was struggling along without them before.
I had been put off from making them, not knowing what to stuff them with, but a 2 minute internet search told me that sawdust was the best option. I bought some wood shavings, sold as bed bedding and this worked well. I used two layers of fabric for wach side, one of calico and then an outer layer, a scrap of cotton upholstery fabric for one side and a scrap of I-don't-know-what upholstery fabric for the other side - much cheerier than the ones I have seen for sale locally! The only slightly fiddly bit was stuffing them, I had hoped to be able to pack in more wood shavings in the ham, but it is curved enough and really helps pressing the curved seams, I don't think I could have got a good result on the bodice without it!
