Hi,
I was at a sew day last week and noticed that when I was cutting was leaving behind a few stitches, so my friend said lets change your blade and guess what, that is what it was trying to tell me
Change your blade
Also she told me to go to Walmart and much cheaper than Joan's. So I went to Walmart and bought Fiskars straight rotary blade 45 mm (5 blades) in package for $15.95 and much cheaper that way instead of using the coupon at Joan for one blade.
Enjoy!
