It's really good! I basted the quilt on my cousin's large wooden kitchen floor. As far as I could tell, not too much overspray stickiness but as I haven't had to live with the kitchen floor post-basting I can't absolutely guarantee 'no mess'. Hopefully if there was a mess the children got the blame ;-)
I pin basted as well - I don't mind pinning at all and this quilt is quite big so I did it to be on the safe side. I think on a smaller quilt you could get away without pinning at all.
I also finished up Mel's bee block - a pod. Her blocks will look amazing when they are all together - pods seem to be all the rage at the moment.
