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.
