When it comes to blocking a doily there are probably as many different ways to do it as there are people crocheting. So here is how I do it. You need something to pin your doily to- I used a piece of foam poster board because it is super inexpensive and easy to replace. I took some clear scotch packing tape and covered the whole front side of it for a bit of waterproofing.
Then you need starch- I used a spray can.
You also need safety pins
I draw a circle on my board so that I have a general idea of where to pin. Next you want to wash your doily. When it is still wet you start pinning the doily down. I have to angle my pins because I pull so hard.
Once you are satisfied that your doily is pulled tight and pinned evenly just spray it down with the starch && let her dry.
Of course if you are anything like me you will be in your bedroom with a blow dryer drying it as fast as you can. After several hours of straight crocheting, I am ready to admire my masterpiece! :)
Once it has completely dried you are free to unpin your doily and fall in love with it all over again!
