Wow, great space. My sewing room has the following items plugged in.
Two sewing machines, two Stella lights, one LED over ironing board, one Ott light over cutting table, coffee warmer (really a candle warmer) , iron, and I have a ceiling fan light. The fan is wonderful in the summer. I use extension cords because of the lack of outlets. Put more than you need because technology is ever changing even for quilters!!
