There are three or four cut-out shirts in their ziplock bags that need interfacing to be applied to collars, facings, and cuffs. To try something new, I set up a table in the living room, made an ironing surface (cardboard cutting board, towels and an old tablecloth) and got busy pressing multiple pieces at once onto the sticky side of the interfacing. I use the iron tip to tack the garment piece onto the interfacing, then cut it out, then press it according to the interfacing instructions.
After everything is nice and dry, the pieces for each new project go back into the ziplock to wait for the day it stops being a UFO and becomes a shirt. I find that I am more likely to sew up a project if the interfacing has been done and I can just sit down and sew. The gray fabric is a new shirt for A and it is going to have contrast cuff and collar lining. The gray has pinky/purple undertones, so I found a scrap of fabric that coordinates with it. It made me think of all the small lengths of cute fabric I have that are too small for a top but could be useful as interesting collar and cuff linings.
