Question about bias blocks
 

I was wondering if blocks that have any pieces cut on the bias will be more likely to pucker when being quilted (on a DSM). My current project has square in a square blocks that look like they're on-point, I'm wondering if that will be harder to quilt...

I have not found that to be the case. I stopped getting puckers once I stopped basting with pins and changed to spray basting. If your sandwich is basted firmly after the top is assembled, I don't think it makes any difference if your blocks have bias cut pieces.

No different than using triangles in a quilt. Once they are sewed to another piece they should be fine. The only time it may cause a problem is if it is on the outer edge of your quilt. Then I would stitch all the way around the quilt before sandwiching

Should not be a problem, just make sure that you have securely basted your sandwich, and as cjsews advises machine baste any bias edges on the outside of the top. Actually, machine basting around the edge of the entire top is a good practice regardless of the piecing technique.

I agree. As long as you have basted the quilt securely, you shouldn't have a problem. The problem with bias blocks is when you are piecing the blocks into a quilt, that the fabric might shift and you would see THAT when you basted the quilt because it won't lay flat.

whenever i do anything on point or with curved piecing, I back it with stabilizer. nothing heavy duty of course, but the fusible light weight prevents all stretching. I use shape flex by pellon. Quilts on point can suffer greatly from stretching. Press well with starch or a stiffener. How you put your borders on can make a big difference as well.
