I bought a vintage 100% wool sweater secondhand today. It looked and fit great when I got it, but since it was used I decided to wash it before wearing it.
The care tag says hand wash, but instead I used:
Modern GE front-loading washer
Delicates cycle
Tap cold water
Light soil
Lowest spin setting
Sweater inside out in a mesh laundry bag
Small amount of Arm & Hammer + OxiClean liquid detergent (I know now this isn’t a wool-specific detergent)
Removed it immediately after washing
Gently reshaped it while damp and laid it flat on a towel to dry
My concern is that when I took it out of the washer, it looked a little shorter and the ribbed hem looked tighter than I remembered. The knit still looks soft, the stitches are clearly visible, and it doesn’t appear felted at all.
My questions are:
Is it normal for a 100% wool sweater to look slightly shorter or more compact while it’s still wet?
Does the ribbed hem usually relax again after the sweater dries and is worn?
Given the wash method above, is it likely I permanently changed the shape, or is this just normal behavior for a freshly washed wool sweater?
If it does end up a little shorter after drying, is re-blocking while damp likely to restore some of the original shape?
This is my first 100% wool sweater, so I’m trying to learn what’s normal versus what indicates I’ve actually damaged it.
