Hi Samantha, if its the 12 week countdown before a show I start off doing 30 mins 4-6 times a week and then up that amount to 45 minutes cardio when I’;m about 4 weeks out. I do a mixture of intervals and low intensity cardio, I hope that helps you :)
I think your 4 together look fantastic, and I could totally see it as all 9. I don';t think you get the full picture of that in the mosaic mainly because it is the same block shown 9 times. My eye pulls in the left (darker) side of each block & I don';t get the picture of the quilt blocks themselves and it looks a little mish-mash which is deceiving.
