Grand illusion mystery quilt

I have made Bonnie Hunter 's last mystery quilt and loved it. The quilt is finished, I should say the quilt top and now the quilting. Basting for me is a nightmare. Everybody on the Internet creates for free motion quilting lap quilts, baby quilts, wall hanging. No one is doing huge quilt. Basting is actually what will make or brake your free motion quilting success.

I do not have a big enough floor surface in my house that I can use to baste huge quilts. And I love making huge quilts. The grand illusion is pinned like you would not believe. See the picture... And yet I have shifting and puckering. So basting with a q snap works for small but not large quilts.

I have a frame but so far would not be able to install it. The take up bar would fast become awkward with the pins anyway. The only solution I see in the future is a longarm quilting machine. The space is a bit of the draw back I have to say...

I do see one in my near future...
