Date: 8/9/12 0:30 AM I made my first purse (yay!) using a fashion weight vinyl. Mostly it came out wonderfully, but when sewing the straps around the d-rings, the fabric became so thick that it barely fit beneath the presser foot, and the bobbin thread snagged and bunched to create a terrible mess. Does anyone know what may have caused this, and how to avoid it on the next bag?
Thank you all! |

Date: 8/9/12 11:51 AM What causes it is probably that your fabric mass and tallness, is just too thick and tall to fit in there, and sew good at all, and the feed dogs can't carry it and move it though even all by themselves anymore. Also, anytime you have too much and too tall amount of fabric jammed in there, it just raises your pressure foot up to the place your machine thinks you are raising it, to withdraw the fabric out of there, and then that means you now have no top tension anymore, even on the upper thread at all, and then of course you get the normal for that, kind of horrible loopies and thread tangles on the bottom side of your fabric, from the top thread having no top tension on it.
Also maybe the vinyl is kind of hard to sew on,even only one or two layers of it, and sticking to your stitch plate too, which probably does not help a whole lot either.
Most times the answer is you have to change your sewing expectations on something when that happens, and decide to sew a different way. With less bulk. Sewing through some tissue paper or such, might just help keep the vinyl from sticking to your stitch plate, but it won't make all those too tall layers of fabric on the straps around the D rings and flatter or less layers of too tall fabric there though. |

To the other poster: thanks for the info! Having no tension on top due to too many layers sounds like the problem. |

Date: 8/9/12 6:32 PM I know this will sound odd, but try giving the multi-layered spot you need to sew a few good whacks with a Sewing Hammer. (Read the comments to the blog post for details about how/why to use a sewing hammer.) It really works.
If you don't have a soft face hammer like the one Kathleen recommends, you can try a regular hammer, but protect the fabric surface before you pound it.

Date: 8/9/12 7:36 PM The thick fabric is raising the presser foot to the point that it is releasing the tension for the top thread.
The results is the same as sewing with the foot up and it does not matter the brand or model of machine being used.
Got a hammer? Cover the thick area that is to be stitched with a towel and give the fabric a good whack. This will flatten the fabric so the presser foot position will be far enough "down" that the tension control does not open. |

Date: 8/10/12 10:22 AM If you have another sewing machine - a stand-by - try that. I had trouble with something a while ago and found a suggestion to use a different machine and it worked. ------ Get the quilters OUT OF MY WAY! |

Date: 8/12/12 0:49 AM One solution is to ditch sewing the straps on and using one or two rivets instead. Go to Tandy Leather, they will show you how to do it. And rivets look cool, too! |
