When sewing on vinyl I use a walking foot. The top stitches are fine, but the bottom stitches are long and loose. What do I need to do to fix this?

You may have to adjust the bobbin tension. Your owner's manual will tell you how. You can also download the manual if you have lost it. It is a good idea to put a piece of tissue paper (the kind they use for gift bags) underneath the vinyl to help it feed through better. The tissue paper will rip right off.
Hi,
The reason that vinyl is so difficult is that it has a sticky surface and doesn't always feed under the pressure foot of the sewing machine. I think that is why your stitches are loose on the bottom. I agree with putting tissue paper under the vinyl to feed it better, and to help it not to get stuck and pull the thread on the bottom stitches.
Have a great day!

there's a dial inside the machine that adjusts the thread at the bottom. It is very important to adjust this properly so as to have the correct tension.
What machine are you running?
Generally three things to try are:
1. Try a sharper needle designed for vinyl
2. Try reseating the bobbin into the machine
3. Try another bobbin (with brand new thread) preferably thread marked bonded nylon or bonded polyester
I tried making blinds a few years ago and my issue was the thread (old thread and not the bonded kind--the bonded kind, wound slightly loose worked fine).
The project failed--not because of the thread issue, but because I did not buy enough(it was a remnant and I thought it would be enough) and when I went back I could not find a color match or a matching remnant. Oh well....I ended up selling the fabric at my yard sale last summer and got more than I paid, so I was happy.
