If it were me, I would take all the paper off the back
and starch and iron the top, then cut the backing and
batting out just a few inches bigger than the top.
Then I would starch and iron the backing material and
lay it down on my carpet and using those T-pins, pin it
down and get all the wrinkle out. Then spray baste it and
put the batting down carefully and spray baste the batting and put the quilt top on top of the batting and smooth all the winkle out and then take out the T-pins and you are ready to quilt it any way you want without any pins to stick you. This is how I do mine. Easy peasy. It does help to
have a friend to help you but not necessary.
