Maybe you are looking for a new knit tech editor, or looking for one for the first time. Here is a list of where you can find editors and when you should reach out.
WHERE TO FIND AN EDITOR
The Tech Editor Hub - I do have promote this resource first, as this is where I got my tech editing education from! But, being unbiased, it is a great resource. You fill out their inquiry form and provide details about you and your pattern. Your entry will be sent out to every tech editor that has taken their course and those who are interested in your pattern will reach out with their information. Don't pick the first one that comes along though - take your time and weigh out all your options!
Instagram - If you just search "tech editor" a whole lot of profiles will come up. The nice thing about instagram is you can check out their profiles and websites to see if they may be a good fit without having to make contact first. (If you're introverted like me, you'll love that!)
Editor Lists - There are actually quite a few websites that have a database for tech editors. The only downside to this option, is the lists aren't updated too often. So you may click on a link to the tech editors page and find that they are no longer in business. Here are a few links to different databases you can check out: Yarnpond, Yarn Database, Knitting Guild Editors, Ravelry Directory, Ravelry Thread.
Ask your fellow designers - Ask who they use and who they recommend. They even tell you who they don't recommend too. This is a great starting place if you aren't sure where you want to start if it's your first time using an editor.
Google - Although this one may prove hardest to find an editor on. Many tech editors either don't have websites or don't show up on the first two pages. (Let's be real here, has anyone really gone past page 3 in Google Search?)
WHEN TO FIND AN EDITOR
You need to get in touch with an editor before you send your pattern out for testing, while allowing enough time for the pattern to be worked over fully. I usually recommend reaching out to your editor at least 2 weeks before you want to start your test knit. Most patterns can be worked through with an editor and completed in one week, but plan for more time in case there are major errors that need to be worked through and to allow time for life to inevitably get in the way of plans.
