I used to use a large folding picnic table. clip the quilt onto the edges and baste the center, then move it and baste the sides. I used large binding clips till my hands wouldn't work them anymore. then i got the curved ones from Quilt In A Day and used a different table.
now i spray baste or use fusible batting.

I love this board, I really appreciate all the great ideas.

Like nativetexan I baste in sections. I have a cutting table and it is only about 36 in wide so I clip the quilt around the middle part first, pin then move it to the edges, clip and pin each side. It has always worked for me.
The plastic clips are the right size for the table and I also use the big black clips that you can get at the dollar store.
I use the bent pins also. Twin size is the biggest I have done, mostly only lap size. I send out my larger quilts for quilting by a longarmer.

I am lucky that DH is a pastor at our church, which happens to be really really close and he has keys. We go to the church and push tables together and SPRAY baste!

I used to do it on the floor. You can do it in sections on a dining room table. I know people that use an old ping pong table, those are pretty good sized.
Maybe you would want to invest in a pair of adjustable tables from Costco or something that you could store in the garage(folded up) and move to the driveway when needed.

The plywood on the bed sounds like a good idea.

Ok I am different. I use the wall in the hallway! Using poster board tacks to hold it at the top. It is the only place big enough.

I either take my stuff to the local Eagles hall (where my mom is a member) and move a couple tables together to baste on or I go to the library. It is about the only time that I get to leave the house ALONE!!

You could also try the VFW.

You have a wall with enough room to put something on it? lucky you. i can't make a design wall anywhere! sigh.

I live in a trailer, Hall is all I have! I just take the pictures down before I start pinning things up.

I have done the plywood on sawhorses, cuz no way, can I get on the floor, but, am starting to quilt in sections, bc this is still hard on the body.
I have a bum knee too...floors are out, after an injury.
sorry, you found that out!

OMG, way to go. I bet that is easier on your back than bending over.

You guys have given me such great ideas. I Also use those big black clips. I think I can use my cardboard cutting board and lay it on the bed and center it and clip it to it. I will move it after I get the center basted and baste the borders after it is stable.
