AS MANY AS MY SEWING STUDIO WILL HOLD.....and I can still close the door.....However on a serious note, I do try very hard to finish EVERY UFO I have by the end of the year....So I can start the new year with out any serious regrets....If I end up with a serious UFO that I just hate and know I will not finish ever...it goes to goodwill and I know someone will love it and finish it....same with needlework stuff.....pass it on, don't let it take up space in both your room and your head.....
