with Sandra Betzina

If a pair of homemade slacks look homemade, it's probably because of the way the zipper was inserted. Sandra Betzina, TV host and author, advises, "Ignore the instructions that came with your pattern. Most are so complicated, you'll give up and switch to a lapped zipper insertion."

In her book Power Sewing Step-by-Step, Sandra gives detailed instructions for converting any zipper opening to a fly front, and in this video she demonstrates the procedure.

In preparation, ensure the that existing extension is 1-3/8 in. wide and 8 in. long. If converting, merely add the extension beyond the center-front cutting line.

LoursPolaire, your buttonhole trick is brilliant. Thank you!

For the Minister's Wife, the zipper is left long until the waist band is installed. Once that happens the seam secures the zipper and the excess can be cut off. Always use a zipper longer than needed. It prevents that little hole that can happen at the top of a zip on skirts and pants. It is also WAY easier to install as you do not have to stitch around the zipper pull.

Thanks for providing the link for it -

I found this video a few days ago and right away, I adapted my dress pants pattern so this technique could be tried. I cut 2 dress pants front and proceeded to use the technique shown. The results were astounding. I had learned to make one of those zippered flies when I started to sew 20 years ago, as part of a haute-couture class. My dress pants flies always looked fine, but they were so much more trouble than this technique. And the top-stitched J-line was always a dicey thing, at best. With this awesome technique, everything fell into place and the finished sample was as nice as the ones I had been making all this time, but in 1/3 the time. Thank you so much! One thing I added: I am not fond of slashing the seam allowance. So, I machine-stitch a long buttonhole that runs from the seam itself all the way to the seam allowance's edge. I can then slash the seam allowance and nothing frays. Again, thank you so much.

Snuzal writes: Well I just have to join in and say I LOVE this. I make a lot of pants, and this is my TNT method of putting a flat fly front zip in. I don't use the video now, but will ALWAYS use this technique, why pattern companies make their instructions so complicated, I'll never know.

morrisbon writes: Thanks for this helpful video. I've bookmarked this video for a reference when I finally put in my first fly front zipper in the first pair of jeans I plan on starting to sew in the next few days. (I'm actually using the Vogue Pattern #7608 that is previously mentioned.) I've put in a regular type zipper before but have always avoided this flyfront style because I could never figure it out! It was really neat to see this zipper actually being sewn. Now here's hoping I can only do it!

sewgnu writes: This video was soooo good! After struggling along trying to work out instructions that seemed to encourage discouragement, I found this video. It was so easy to follow,- watched a little, then hit pause - did the step, hit play and watched - hit pause then did the next step and before I knew it, the zipper was in. Thanks very much. You're the best!

Now, I can do more sewing without being afraid of messing up.

Thank you for having this invaluable video for me to look at if I feel stuck.

I also love the fact that I can email this to myself and have all the videos I need in my email folder for refrencses.

Again, thank you sooooo much.

Grannie_Annie writes: Thank you so much for this video instruction. Fly zippers have been my nemisis for decades. I'd start out making a fly zipper and then give up, sew the seam in the front and make a back zipper........grrrrrrrrrr.

Thanks to you, I have two perfectly sewn fly zippers and now have the choice of front, back, or side openings. I'm the clearance queen and love boasting at work that I made my pants for less than $4.00. It helps to boast if the zipper looks good. smiles.

Thanks again

canardlysew writes: I hate doing zippers, because the way I was taught in school back in the 60's was so complicated using a sewing machine that I always had someone else do it for me. I just bought a pattern for a pants suit from Vogue which I would love to make and am grateful for this video, as it has shown me a completely different and easier method to use.
