Basting a king size quilt
 

This is how a do a king size. I don't have floor space and if I did the dog or cat would try and help and make it worse. So I use fabric strips to pin and stretch. The bottom 12 inches aren't basted but I can do those once I get some quilting done. It's not pretty but it works when you don't have another way to do it.
Edit...I resized pics and hit the upload button....I give up.

and the front

I don't know what I did different! Must've been how I was holding my mouth!

Wow, that is a big quilt! We all do things we must do to make things work for our spaces. So far it's looking good. Just keep going and it will actually get done. :cool:

I use painter's tape and tape my backing to a wall. Then I spray stick on my batting and finally my top. It's a lot of work. I just bought pool noodles and am trying them. Right now my top and batting are wound on noodles, I just need to make my backing.

Your method looks like it would be a challenge to keep out the wrinkles.

Wow, that is some super-sized quilt! A big job for sure, but your method works for you and that's half the battle. Love your fabric colors.

I use this method for all my quilts. It works great! No crawling around on the floor.
