Reverse stitching not working

SOURCE: I have an sx 2122

Hello

I'm thinking it's that you have to hold it down the whole time you want to stitch in reverse,if not,

The most common cause of machine misbehavior is - believe it or not - the needle. So swap it out. I don't care if it is brand new --- sometimes they are bad from the manufacturer. It is such a simple fix and one that you need to learn right now -- when in doubt -- change it out!

Be sure to install the needle the right way. There is a flat side that needs to hit the adjusting screw so that it doesn't wiggle around when sewing.

Next - be sure that you have threaded the machine correctly - go back and look at the owner's manual and re-thread the machine -- leaving about a 2-3" tail after going through the eye of the needle from front to back.

Now - for the bobbin -- is this the bobbin that came with the machine? If you purchased new ones - are they the right size - it doesn't go well with the wrong size bobbin. OK - now, did you wind it on the machine or by hand? If you did it by hand -- is it evenly, tightly wound. Are you using standard thread or are you trying a specialty thread?

Did you put it into the bobbin case / holder going the right direction -- machines can get pretty finicky - so make sure that it is unwinding the correct direction. It must turn counterclockwise. If the bobbin is in backwards or upside down - easy to do on some machines, and impossible on newer models, it can cause a great deal of trouble.

Also, make sure that you have not inadvertently bumped the tension adjuster for the bobbin. This can be a stick like adjustment at the top of the machine - may be an adjustment on an LCD screen - it varies depending on the model.

Again leave a 2 - 3" tail and put it in place correctly.

Make sure that the presser foot is up - and that the feed dogs are engaged.

Now - using the hand wheel on the right side of the machine - and holding on to the upper thread tightly - move the needle up and down once to bring up the bobbin thread through the throat plate of the machine. The bobbin thread will be caught up and a loop will be visible between the presser foot and the base plate. Gently pull both threads up and to the back of the machine - out of the way of your sewing.

When you begin working on a piece of material - hold both threads firmly to the back and take the first few stitches slowly to make sure that they are not going back down the throat of the machine. Be sure NOT to try to start at the very edge -- begin about a 1/8 to 1/4" in from the edge. If you are doing quilt work and only using a 1/4" seam - then back up after starting and come forward again. If you are using a traditional 5/8" seam allowance - no worries
