This is not an easy question to answer because there are so many variables.
For example, the way you sell will depend on what your specialty is, whether you are selling individual one-of-a-kind things or catalog-type items, the amount of volume you can produce, the amount of volume you want to produce, whether you want to make a living or just pocket money, etc.
My wife sells her stuff 4 ways (Jewelry)-
Art/craft shows- These shows are not very lucrative, so you have to do a lot of them to make a living. We make between $700.00 and $1,000.00 in a two-day show. The benefit of shows for us is advertising and networking more than it is sales. We make more money later from the people we meet who become regular clients. We only do 2-3 a year. We are about to start doing major wholesale market shows like the Rosen show.
Wholesale through a sales rep- Sales vary based on the economy and range between $500.00 and $10,000.00 per month. Quite a range. But we like having people out there doing the sales work for us. My wife refuses to sell her own stuff to stores. Cant handle the rejection. We are represented by 4 traveling salespeople covering 11 southeastern states and Texas. Sales reps typically get 15%. We now need reps for the west and the northeast.
Direct to clients from our studio at home- Word of mouth is awesome. Sometimes I feel like a drug dealer with people coming by, hanging out, checking out the goods and leaving with a little bag. Anyway, this is the easiest way to sell because people come to you and are ready to buy.
Home shows- This is my favorite. We do between 1 and 4 home shows a month. The hostess buys the refreshments and sends out the invitations. We typically sell $700.00 to $1500.00 in a two hour period. The hostess then receives 10% of sales in free jewelry.
But, to do it all right, we incorporated, got serious about keeping the books/records, providing professional service and invoicing and all that goes with it, making a nice wholesale catalog, and producing sales samples for the reps. Now the biggest hurdles are finding the piecework firms we need in order to boost volume, and keeping new designs on the cutting edge. Seriously selling your stuff means hard work running the business end, as well as producing consistent quality products.
Sorry so wordy. Hope this helps.
