Today I will show you how I'm usually stretching my all white doilies. After making it, it must be washed in some whitening washing powder and to be taken into the starch melted in a cold water. I used to do it a starch which used to white curtains what helps a doily to keep the final shape for longer.
After such washing I very delicatel turn it into the towel to dry a little. And finally I take a lot of pins and a towel to be able to stretch a doily on it. I always start from the middle of a doily. All stretching I tried to show on below pictures:
And here you can watch the result of all work:
Thanks for you time!
