Here are a few tips for great looking pillows. I do lots of custom interiors and everyone wants pillows and more pillows. Here's what I do for a great looking pillow.
When you sew your pillow square make sure you reinforce your corners. I restitch the corners when I'm done. When completing a side - Don't Pivot at the corners. Sew all the way off the fabric, cut your threads and sew the next side. When done, clip your corners just above the meeting threads and trim a bit off the each side at the corner so it looks like a point. Press all seams open before turning! This eliminates creased sides and the tips of the pillow are nice and pointy. If using a pillow form, Trifold your fabric and make a cover or add a zipper opening. Make your pillow measurement about 1/4 inch smaller on all sides. Now the form will fit tightly and your pillow will look smooth even when "abused". For those of you who like to use stuffing - separate the fill first, stuff the corners then stuff the middle. I use a wooden spoon from the kitchen. The spoon keeps your hands out of the hole and keeps you from stretching the opening. By the way, it should be at least as big as your hand. :-) Close your opening using heat and bond. The finish is seamless and nobody can tell where you closed it.
