i use my 6" fiskar scissors, they are sharp to the point and work great, i thought my embroidery scissors were too small to cut these out and pretty much baby my embroidery scissors, i love them so much...i only do little snips with them...(the stork ones) i have a little bitty pair of very sharp 1 1/2 " scissors my daughter picked up at Michaels one day that would probably work great...they are just never where i need them. the fiskar's are always within reach...
and i think i have a couple pictures of other blocks i've used the same technique on...i'll try to locate them
