I'm fortunate... have a glass top dining room table. Makes quick work of laying out material. Then, I use the curved safety pins to "baste" my layers in place.
If it's practical, you could purchase 2 pieces of glass for top of your table... not very expensive .. maybe $40 or so. Makes a great working table.
I have added glass to ALL my tables (end tables, coffee tables, night stands). Does away with fear of someone leaving white rings on precious antiques. CHEAP to do and takes away the worry.
HAPPY QUILTING !!
