I love it!
In the end I decided to go with red, white & blue variegated thread because I had so many spools of it. It's a good thing I did because had I gone with red, I would have ruined a $10 spool of Aurifil instead of a half empty spool RA. I accidentially put Fray Check on the spool instead of Sewer's Aide. I realized I did it the moment I squeezed the bottle....thankfully!
