Skill. If you’re going to sew for other people, your skills need to be far above average. If you’re a beginner or an average seamstress, wait until you improve their skills before attempting to earn money in this type of business. If people are going to trust their wedding dresses or their favorite sports jacket to you, you must be able to handle them with care and the utmost skill.
When it comes to at-home income, selling your unwanted stuff is the definition of “low-hanging fruit.” Even if you’re resolutely intentional in your purchasing habits, you surely have possessions that you can do without: old kids’ clothing and toys, disused sporting goods, out-of-fashion wardrobe accessories, electronics, entertainment, valuable but non-sentimental keepsakes such as watches and jewelry, broken-in furniture, dusty tools and outdoor equipment, and perhaps even big-ticket items like a motorcycle or second car.
Sometimes it is necessary to change your perspective in order to see all the skills that you truly have. Do you play an instrument? If so, you could no doubt teach music lessons to young people (or anyone) in your community. All you'd need to do beforehand is a bit of lesson planning. You can even offer a discount for the first 10 people who sign up in order to get your name out there and help spread the word.
The best way to get started in this field of online marketing and selling is with proper training. There are a lot of training options out there but many of those have the disadvantage of being low quality or incomplete. One particularly good choice for training in online marketing is a site called Wealthy Affiliate. This was actually where I learned most of what I know about making money online and I’m still an active member of the community.
Note: There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and not having impossible standards for cashing out. As always, be careful with your personal information. I recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.
