Also, are you squaring up your blocks before you sew them together? That helps and it also lets you know what issues you need to adjust for to get the seams to match (like baggy block on the bottom, etc)

Jacqueline de Jonge ( Be Colourful Quilt patterns), machine bastes those seams you want to match. Match them up, baste for maybe 5 stitches, remove from machine, check the seam, if it's good, reset your stitch length and stitch the whole seam. It works.

All these methods are great. An accurate 1/4" seam is essential and on triangles with seam lines going across on the diagonal starch spray before you even cut helps to stop fabric from stretching.
If all fails the quilting will cover up a few misses.

I usually pin before the seam I'm sewing. When I tried pinning on the seam it would leave a space the width of the pin. Sometimes tightening up one seam or the other will make the nesting easier. I put the pin on the left side as that part will go under the needle first. I try three times, if the seam still doesn't line up right. I then go on.
If the seams are open I will turn it like it is opposite of the other seam, pin it and then release it to be open again. I do that with a seam allowance that is going the opposite way too.
Washing and drying the quilt when you are done helps hide a few mistakes.

Glue stick AND the washable white glue (comes in clear now too ). I got a special bottle and needle applicator for glue on ebay. It dispenses just the right amount and is easy to handle. I have no trouble with clogging. I got some extra tips because I already snapped one off . Easy to take along too. Here is one of several sites if you want to try it. It's inexpensive and the glue goes right where you want it to: http://www.ebay.com/itm/2-Bottle-Sol...item27dc5b6ea6 and if you want just the extra needles: http://www.ebay.com/itm/Blunt-dispen...item3a8d2ff2dc. The bottles have luer connectors and many sizes and gauges will work.

I don't use pins or glue. Finally discovered that if I align the seams with the top seam nestled ahead of the bottom piece, the machine will feed over the seam perfectly about 90% of the time. The other ten percent is probably me trying to go too fast! I imagine one would need to test their own machine to find its magic alignment! Good luck

I've been using glue for binding forever. Why have I never thought to use it to match seams? I'm so mad at myself.

The finer the pin the better. "Clover Patchwork Fine" pins are the best and they have glass heads. If you are careful you can sew over them. I ordered mine direct from Clover's website. The pin heads are translucent yellow and blue.
