What is the best way to block knitted items made with man-made fibers?
yes, i would think that's correct
Yeah I think the acid reactsif you need to use metal, use stainless steelIf you are wrapping something, use plastic wrap.
Cans of acidic liquids will corrode through in a couple of years or even lessI've seen it personally when my juice I never touched just blew out and made one heck of a messI'm sure tomato juice will do close to the same thing as it is acidic as well.
Never Cover or Save Food with Tomato's in it in Aluminum Foil
Look at the care instructions on the yarn to see what you can do and check out the link belowIt has several different options for blockingThey suggest Wet Blocking tho for man made fibers: Wet Blocking Wet blocking knitting is an appropriate method for blocking man-made fibers, novelty yarns (except for some very delicate novelties that may fall apart when wet—check the label for care instructions and don't wet anything that says it shouldn't be wet) and some wools and wool blends if done carefully (remember heat and agitation can cause wool to felt)Dampen the knitted piece so that it is wet but not drippingSpread the piece out on a towel, sheet or clean garbage bag (the bag won't absorb water, allowing the piece to dry faster) on the floor or a spare bed where it can sit undisturbed long enough to dryGently stretch the piece as needed to meet your blocking goalsIf you're trying to get a piece to the size or shape the pattern recommended, you might need a ruler, tape measure or yard stick to help you outUse rust-proof safety pins, straight pins or T-pins to hold the knitted piece to the towel or sheetAs the piece dries, it will retain the shape that you gave it.
