Help with first quilt - ok, this is probably a really dumb question, but I am stuck on putting the last two borders on my quilt top. I have sewn the side borders and had some slight puckering/pleats in my seam. I had to rip out a couple of times, but I think after I quilt it hopefully it won't be too bad. My borders are attached to long strips of sashing. The pattern calls for me to put a 5.5" x 5.5" block at the ends of each of the top and bottom borders. When I measure for these borders, do I measure to the end of the seams from the top and bottom of the quilt? In other words, I ignore the already sewn on side borders? I added 1/2" to the width of each of my side borders. So after I sew these last two borders on, do I just go around and make sure that it is square and trim off the extra width? I know I have so much to learn with quilting. I really enjoy sewing, but honestly I'm getting a little stressed over my first quilt. Thank you all for your helpful advise!
