These are a bit long but could help save some time and trouble later. Hope it helps. Maybe you can find pics somewhere else or I can try to do a tute if you need pics. Strip quilting is the way to go...
For triangles there is a technique I've seen demonstrated on one of the PBS quilting shows which we no longer get here. I think it was Eleanor Burns' show. This is not the best tute but really good info.http://www.quiltingpassion.com/tutorials/HST/hst.html
There is a similar technique for 1/4 square triangle with the hypotenuse on the straight of grain instead of bias.
I haven't tried doing any quilting stitching in a long time. During my attempts this past week I'm reminded how tricky it can be. My machine doesn't do 1/4" seams very well. It's the machine not me.
So I found myself wishing I has slightly over cut and then trimmed. It's much easier.
Tip2: To keep the machine from eating your fab.
a) My faceplate has a small piece that can be removed, rotated 180, replaced. One end is for zigzag, the other for straight stitching. Unfortunately I have a bad habit of forgetting to rotate it for zigzag. Yep, broken needle! But worth it for quilting.
b) assembly line stitching. Just feed the fab one after the other until you get to the end. Then feed it a scrap and leave the scrap in place. Stitch off of it onto you fashion fab the next time you start. Easy to cut the fashion fab squares apart when you are ready to lay them out again. Or leave them together and stitch the other direction.
