im trying to redo my blanket....suggestions would be appriciated.

I never liked working with the silky fabrics for this exact reason. Without seeing what you are talking about..a trick I learned is to use a very light weight iron-on interfacing and iron it to the back side of the silky fabric... that gave it a bit more "substance" so that the machine could grab on to it and the needle had a bit more "weight" to push the needle through so the fabric could stay firm while the needle sews along. They have all kinds of threads these days.. back in my time... it was polyester... but later cotton covered poly came to town and I used that mainly for the safety of my machine - plain poly leaves slightest bits of "fluff" in the bobbin cage and that complicates the sewing. So I changed to cotton covered Dual Duty thread. That might be somethin gfor you to look into.. do you have the right thread for working with silky fabric.. and the needle.. the thicker the fabric the fatter the needle needs to be - to a point...fatter, stronger.. forget the exact term. The machine needles went up in number. If I remember right 11 was the main needle size for most fabrics.. and went to 14 for denim. Maybe get a lower number needle so it only makes a much smaller hole in the fabric, which would mean much less tension on the needle to get that thin needle in there so it doesn't puncture as hard...which is easier on the fabric and stops the pulling of the fabric. Or you could see about doing it all by hand. Again, not seeing what you are talking about is a bit hard to advise.. but by all means.. restore your blanket that holds your memories!
