my liners won't stay put
After trying out some different styles and fabrics for making liners I've decided I most like flannelette (just 2 layers which I sew inside-out, turn right-side-out then overstitch). For the pattern I've just copied my disposable liners and added wings. I've found them more comfy to wear in that they don't irritate the skin. However, I'm having a problem that they just keep sliding backwards in my undies every time I walk (think my big butt is trying to eat them). I wear boyleg undies and the further back they travel the more they gather the fabric of my undies at the back and start to get uncomfortable. It could also be a problem that I tend to have a forward bleeding pattern so won't get the coverage where I need it if I actually use them whilst I'm on a period.
Short of safety pinning them into position is there anything I can do do make the liners stay put?
