Hot glue your dowels together if needed. I glued the two ends together at the very end and then also placed glue around the outside where the two dowels met to provide extra support. Hold the dowels together until the glue starts to get hard and then let it sit for 30 minutes or so to completely cool and dry before trying to build your sukkah.
Once all of your poles are created, place them in your stabilizing materials, whether that's plant pots or floral foam bricks or something else you've decided to use. You can now place them where they will stand in the room.
Once the dowels are in place, tie one end of the tulle to one pole at the top and string it the pole to the left, letting it droop a bit in the middle. Repeat with the pole to the right and diagonally across, until all the poles are connected and you've created a very basic "roof."
On three sides of the sukkah, drape more tulle over the "roof" pieces so that they touch the ground. These are your "walls."
Arrange any furniture, such as chairs or small tables, within the sukkah to support the dowels and to use while you celebrate sukkot! You can use the twine to attach the dowels to the furniture as needed.
Lastly, decorate with any decorations you'd like to use. I used fall produce and fake flower/greenery, leaves, candles (safely!), string lights, ect. The dowels are a little dainty, so I would only recommend trying to stick anything very, very light to them.
