How to research a mug or clothing idea before you list it

  1. Start with a buyer and an occasion. For a teacher thank-you mug, compare several specific phrases in Etsy Marketplace Insights. Record searches and listings for each.
  2. Check timing. Look for a repeat summer peak in UK Google Trends. That gives you time to make a sample and photograph it before the occasion.
  3. Check sold prices and your margin. Compare similar mugs in eBay Product Research. Then enter your selling price, print cost, postage and fees in the free product profit calculator.
  4. Make a sample. Prepare artwork at the supplier’s template size, check it on the actual item and photograph the finished product. See our UK mug fulfilment guide or browse clothing and fulfilment suppliers.
