A number of years ago I made this quilt for my bed. Then I got 2 new rescue dogs, a great dane and a rottie mix. They took to jumping on the bed and sleeping there. You try keeping them off the bed!!! Anyway, you can see in the pictures what has happened. I do have strips leftover so I can repair it. But how do it without totally taking the whole thing apart. It is serged around the edge and hand tied. I really don't want to cut off the serged edge, undo the ties and then replace the bad strips, but may have to do that. Any better ideas?

Applique something over the BAD places. I used to raise Great Danes and always put a cheap blanket over my quilts so that they didn't tear them up with their toenails!

Maybe a wide zig zag to cover the open areas , that or take the material you have and applique that over the spots

There are too many places to applique over. And dumb me, never thought that would happen when the fleece side was up. Now I make my own fleece blankets from sale fleece at the store and wash them a couple times a week. What we do for our beloved pets. They do have their own bed ( a queen size camper mattress) on the floor but would rather sleep with me.

can't you just sew the matching colours over the torn pieces to match the strips that are torn I used to patch things all the time, cut the strips a little bit wider turn a fine edge under pin them in place and machine sew around them it would be the easy way out may not look as good but if you are careful and keep your stitches very close to the edge you wouldn't notice it so much, or you could do all of the above and hand stitch it in place

you do not have to cut the serger part just cut the thread by using seam ripper. cut the looper threads and i don't remember if it the front or back and pull the thread then use seam ripper and cut the straight stitch .

If it is a 3 threader you will have 2 loopers and one straight , but a 4 threader it is 2 loopers and 2 straight

I use to sew and that is how i did mine when i had to remove my thread

Yes, I know all that; have done it before, but since it is just for me I don't want to spend all that time trying to find the right pulling thread; faster to just cut off the serging and then re-serge when finished. And as far as patching is concerned, I thought of that too, but since the fleece is considered the front I don't want all that stitching to show . I know I am just making this more work than it need be; but it has been sitting in the repair pile for at least 3 years and it's time I get to it.

Use invisible nylon thread and zig zag the areas together.

The only thing I can think of that will not show on the back is to hand applique the pieces on the front.. if you use an "invisible" stitch it won't touch the flannel and will be a virtually invisible repair.

When I use to sew quarter inch I had to do this on 2 of my quilts. Don't do that anymore, use the reg sewing stitch for clothes.
What I did wAs PUT SOME FRAY CHECK AND THEN SLIPPED THEM INTO next piece like they were or slip stitch or invisible stitch and slip the pieces next to fabric that it touched.
