Fuzzy Feet from Knitty

I made a guage swatch using the yarn I am using and I think my guage is off for this pattern by about 4 stitches. Should I just got up one needle size (the largest circulars I have) or should I try and alter the pattern? It seems very hard to alter this pattern for my guage (I tried but it was very confusing). It seems like since these are felted it shouldn’t matter that much, right?

Please tell me your thoughts.
