I just got a pfaff 7570 so excited because of the IDT dual feed on the pfaff and i just started machine quilting (been hand quilting for 4 years). i'm working on a project and was able to quilt a couple pieces no problem. cotton fabric on top and bottom, fusible fleece inbetween. I tried to run a straight stitch down this piece about 10" wide x 50" long and i got what i guess it called puckering. the back of the piece which is next to the feed dogs is perfect. but this is the top of the fabric that sits against the fleece that isn't fused. i relieved the tension that didn't work. i even tried to start in the middle instead on the ends that didn't work. i've redone this piece 3x getting worse results everytime. i take it off the machine and here is what it looks like. i can not figure out the problem. i'm using just my regular foot pfaff foot "0" with the idt on. so its feeding fabric from top and bottom which means this shouldn't happen! help anyone.

Are you applying any side to side tension with your hands while sewing it? I find I get better results that way.

Is there another foot to be used with the dual feed? Bernina has a dual feed but the foot is different. I am not sure how your regular foot can provide dual feed.

Bernina has a dual feed foot AND a walking foot for quilting. But they're different manufacturers. I'm sure someone that has your same brand machine can give you tips.

I had the same problem with fusible batting. I won't be using the fusible on big projects anymore, I will stick with basting spray and safety pins.

I have never had a problem with my dual feed. I have used polyester and cotton batting, but never fusible. I do have a problem if I use basting spray. It seems to gum up the needle and cause skipped stitches, so I only use safety pins.

You need some kind of basting. If I read this right, you fused the back to the batting, but not the top? That is probably why the top is shifting on you and puckering.
Try spray basting or pinning the top down too :wink: :D:D:D

spray baste or pin--just check your idt foot is engaged the black attatchment sits at the back of the needle shaft needs to sit low into the back of the foot you have on--it can be dissengaged and sits higher and away from the foot

If you have a darning foot try that. It doesn't put any tension on the top so it can flow through easily.

I'm sorry i didn't mention this, yes I did baste the entire thing before I quilted it, with pins. I always baste the fabric.

also try lengthening your stitch length just a bit.

I have the same machine and love it. I lengthen my stitch and use tension on both sides and I don't seem to have much of a problem. I have done all sizes on it. I mainly use safety pins to hold mine together while quilting.

Ann L,
By tension on both sides of fabric... do you mean to the right and left of the needle or tension to the front and back of the needle?

what stitich do you use. I was just using the first stitch on the machine....?
thanks

I just lengthen the stitch so it isn't such a tight stitch, I want to say a 3 or 3.5 length, and tension on both sides as it is feeding through.

what stitch are you using since you have the same machine?

sorry still don't understand where you are applying tension....one hand behind and one infront of the needle i assume? thanks!

Try inverting the sandwich. The backing fused to the batting on top and the not fused at the bottom. It should reduce or eliminate puckering.

I have a 7570 and this is the top tension. Mine has 'settled' into a 1 to 1 1/2 on the top dial. I had to just play with it on different fabrics when I first got it many years ago.

Make sure your IDT is engaged and make sure that the foot you are using has a slot in the back to allow the IDT to meet the fabric. I hope I made that clear. If you need a picture of the foot to use , I can send that too. Just let me know. I know it is frustrating when you get a new machine and can't get it to behave. When you get used to the 7570, you will LOVE it!!!

yes i have the "O" foot which is standard and the idt engaged. I've had it about a month but just started machine quilting. i did the other couple pieces of fabric for this project with SID foot on a quilted block and it was fine. I didn't turn the tension down that much. I thought below 3 would be a mess. I can try down to 1.5 like someone said also. I also just read somewhere about using a Straight Stitch plate might help i did purchase one but didn't put it on.
Those of you with the 7570 which stitch are you using on your machine? is it the very first stitch or another one? if so let me know please.

I use the one that defaults when the machine is turned on. I think it is the 1.

that is what i was using! ok thank you. the manuals are horrible! and many say the same thing. i have the workbooks but they aren't instructions per say. its just frustrating when you can see the problem and can't figure it out no matter what you try and it worked fine on 2 other quilted pieces 10 minutes before that were sandwiched the same exact way. they only difference is this is a LONG piece of fabric.

Sometimes to change the needle will make a great difference. Give that a try. It won't hurt anything..

I am glad you like you Pfaff machine I have one and just love it. I just do hand quilting on my quilts excecpt the borders and I machine quilt them. I machine quilt baby quilts and wall hangings but have never tried a BIG quilt
yet. Keep trying.

One hand on each side, right and left of needle. Holding it flat or rolled.

ok i just redid it. 4x seam ripping is getting old! i changed my needle plate to a straight stitch needle plate, i lowered the tension a bit more and it came out fine! THANK YOU EVERYONE. i don't like to change all the variables at once then I can't see the problem for next time. So i took a scrap after i was done and kept all the settings the same and then changed the stitch length like Ann L said. I think I will also do this next time too. I've read the straight stitch plate really helps to keep the fabric in place too, glad i ordered it! thank you so much this board is fantastic and quick!

glad you were able to get it figured out.
