I had a denim tragedy. I'd made a beautiful pair of jeans, which is a large investment of time (because I'm slow). As I tried them on to photograph them... the zip pull disintegrated. After some tears, I unpicked the zip. Then I hand-sewed in another higher quality zip. The fly will never look quite right.
|It's just not the same.|
The zip I originally used was a no-name special. It wasn't particularly cheap in price, but it also wasn't a YKK or RTW-style zip. Yes, other cheap zips have been successful. But would this one have failed, if I bought a proper brand to begin with? Less likely, I think.
What's the solution?
Using the powers of Google, I bought about 20 YKK zippers from ZipperStop for about $50 including shipping. Brilliant! This is both cheaper than Spotlight, and less likely to end in disaster.
In summary: quality hardware and haberdashery reduce the risk of failure.
This lesson is not limited to zips. If your thread keeps breaking or shredding, and getting messed up in your machine... try a higher quality thread. I have few problems with Gutermann or Metrosene. Cheap elastic tends to lose its stretch. And fabric with a high polyester percentage seems to pill and fray quicker.
Don't let your materials spoil your hard work! I think it's better to have one hard-wearing pair of jeans than two cheaper ones that fall apart. Your time is invested in that sewing, too.
