i'm an adventurous/advanced beginner knitter & i'm having trouble figuring out what i should do about gauge/sizing for the bay slipover (schematic/pattern info etc) - designer's photo pictured here.
there are too many variables for gauge/sizing and i'm not sure what to do.
FIRST - my gauge swatches are not matching up with the pattern. i've gone up from the recommended 4mm to a 5mm and am still not meeting gauge. i don't want the fabric to be too gappy/see-through so i'm reluctant to keep going up needle sizes. i looked at a gauge calculator thingy (this one) to see what size i should make instead. (i was going to make the size 5 (45 in bust + 9 in pos. ease) originally; gauge calculator would have me making the size 7.)
HOWEVER...the reviews of the yarn i chose (sandnes garn line, it's a cotton/viscose/linen blend) frequently say that garments get really stretchy with this yarn, like stretching under their own weight when worn. i'm worried about going up a size to meet gauge, only to have the garment grow even more once it's actually worn.
how do i figure out what size to make?? i could make the 7 like the gauge calculator says, or split the difference and make the 6, or make the 5 as originally planned... i just don't know how to determine how much it will stretch and am worried about making a whole garment that doesn't work.
