If you have a strait stitch only sewing machine but wish it would do a zigzag stitch, you're not alone. I feel the same. There is something you can use to make your machine more versatile that is easy and inexpensive. I love my vintage beauties but also like clean seam finishes and making bathing suits. Both are best with a zigzag stitch. To solve this I tried a little gadget called a Chadwick Zig Zagger. The Chadwick works like a ruffler and does indeed make a decent zig zag stitch. That said, it has limitations. The stitch isn't as good as a built in one nor is it as easy to adjust. Here's a picture of it: Chadwick Zigzagger Zigzagger with 1889 Singer VS27 The one I have is for low shank machines so that includes several models. Older Singers like the 27 shown here, 127 and 128, 99's, 66's (except the back clamper Model 66), the featherweight, 201 and class 15's. My Pfaff 131 works really well with this and so does the Elna #1 Grasshopper. Singer made their famous zig zagger but I have not used one. If some one has one and would like to comment that would be helpful. The Singer Zigzagger Attachment. By the way, this is bait for a Singer 301. Maybe if I have this this around the Singer 301 Machine will be along soon. How to use it The beauty of this little Chadwick is that it fits on quick and easy. It is sort of like a ruffler. Remove the presser foot. The hook fits over the needle bar screw as you fit the zigzagger to the presser bar. Replace the thumb screw. Start sewing.....That's it. Zigzagger fits nicely on the Elna "Grasshopper" Example of stitches made with the attachment on strait stitch machine. There is a tiny screw on the back that adjusts the width of the zig zag. It also comes with a guide to use a zig zag for lace insertion or edging. For the limitations they have, Chadwick and other zigzaggers really make using an older machine so much more practical. They are small and fast to put on. If you see one, Get it!
