Gauge swatch question
I just got some lovely new yarn to make a pillow case with. I am going to do a gauge swatch to determine how many stitches etc..
My question is, once i do the swatch, wet it and dry it, then measure, can I unravel it and use it to start my pillow case?
Could I perhaps just gauge it without wetting it? I don't want to use up the yarn on the swatch as I might not have enough to finish the project then.
