So, finishing is in progress this weekend. I was sort of dreading this--but once all the backstitching was done, the actual assembly has been going very smoothly. I really like this sort of finishing actually. As this is my first 'mattress' pincushion, I do have a question--what should I stuff it with? I have lots of the sort of wispy stuff that goes into pillows and I have some quilt batting which is thicker. I was wondering if anyone uses matte board inside to give it a little more structure and weight? I contemplated using the stuff you iron onto the back of the linen as well, but I opted not to (as I would have to dig through bins to find the stuff). Any suggestions? I will hopefully finish it later this afternoon after I get chores out of the way, so any input is welcome.
