Thanks for all the suggestions. The quilt I'm starting on now has something like 7 borders so I'll have plenty of chances to put them into practice.

I also used to use starch until some one told me that starch attracts silverfish, which are common in our area of central Oregon. I hate bugs! I now use a spritz of sizing every time I press (not iron), and I have no trouble getting every thing to match. I used this method when I made my big quilt (110x112), and every thing fit! It does make for a crisp quilt, but I do not hand quilt, so no problem. It helps when machine quilting so the fabric is less likely to "scootch" on me. The first time I launder a quilt, I get a lovely 'bloom' of the quilting. I hope this helps.

I always attach the sides first.

i was told to set the seams before pressing the seams that it is suppose to help with the wavy problem and not to drag the iron just press

this is the way I put mine on too

Sharon Schambers has a tut on this on You Tube. She tells how to avoid wavy borders. Check it out.

Sorry if I am repeating what anyone else has said. It is late and I'm to tired to read everyone's.

I press with spray starch and steam
I cut down the selvage (not across) it does take more fabric, cut I have a drawer of leftover border fabrics, pulled out 2 today for a scrappy log cabin.
I measure the top and bottom( or both sides). If I running short of fabric I put on the longer sides first.
I have the quilt folded in half, and fold the border fabric in half.
Pin in center and each end, space in the middle (between pins) and pin again at least 2 or 3 depending on the length. I ALWAYS stitch with the border on top, I use a walking foot when attaching my binding.
Let us know how you make out, hopefully with all the tips you will get the results you are looking for:)

I second that! Very important to see that the material doesn't get stretched.

Scissor queen, if you don't put your quilts in rows, how do you put them together?

It's kind of a long explanation and it's on page 2 of this topic.
