seam coming apart
 

One of the seams in a block on the top of my quilt is coming apart. How do I fix it? Is there a way to sew it closed without the stitching showing? Thanks.

Depending on how large the opening is, you could slide a small piece of fusible interfacing underneath and press it. You can also use color-matching thread and small whip stitches to close the hole.

I agree with Tartan. Try doing a ladder stitch.

I would use a tunnel stitch. I am not sure what a ladder stitch is. Maybe your part of the country.

I fix vintage quilt tops all the time and I use the same invisible hemming stitch I use on clothing. Sometimes I use nylon thread that is invisible but mostly I use cotton thread to match the fabric. Good luck.

Silk thread is very good for hiding stitches. I use it for applique for just that reason. If it is at the edge, can you take off the biding at that spot, repair and then replace binding?

Francis does a stitch that doesn't show at all on her applique. She goes beneath the top layer of fabric and just slightly catches the bottom fabric and then come out at the fold of the top layer of fabric. It hides the entire stitch. Good luck. Usually when that happens to me I find that the entire quilt is actually falling apart and I'm left to either use the entire quilt as batting for a new quilt or if it is a family heirloom to genty sew a transparent netting over the entire thing to hold it together for awhile longer.

I am just facing a similar problem in a quilt I made for my daughter. All of the fabrics are cotton, but for some reason, one fabric has frayed so badly that all the blocks using it have frayed right out of the seams. At first I thought some of my seams were too skimpy, but looking closer, it was only this one fabric and some of the fraying was a full 1/3" or more, so beyond the seam line.
To repair it, I am folding the frayed edges under using fraycheck and letting them dry, then I am using a hand stitch to seam the edges back together. If I were at home, I would definitely use iron-on fusible for reinforcement, but have none available here.
