It’s hard to say what sort of sales rate is reasonable or average for a new Etsy store. I spend a fair amount of time in the team forums, and the general consensus I’m getting is that it’s really hard to make any/many sales for smaller shops, but that larger shops (100+ items) tend to make several sales per week. Given that understanding, I have set a goal for myself that I think is aggressive but achievable. Continue reading »

Here’s what I’ve learned so far. Continue reading »

Collaboration is encouraged, but even if you end up working on something alone, it’s a great way to spread your excitement about whatever interests you at the moment (and it’s a nice perk to the job).

This week, my project was to get some LED strips unboxed and working. The strips are flexible circuit boards, with full-color LEDs dotting one side. Each “LED” is actually three LEDs clustered together (one red, one green, one blue), and with 21 control bits, they can display more colors than the human eye can distinguish. I bought a variety of strips, with different features, and I don’t know exactly what I’m going to do with them, but step 1 is to learn how to use them. Continue reading »
