At least, it didn't stop them 50 years ago~!
Twinprufe put out a series of Spring Knits, and this little cardigan looks adorable - even if it's knitted in a not-so-Spring-friendly wool.
At least it's a light fingering weight.
To fit: 32-34-36 inch busts
Yarn: Light Fingering weight (3ply)
Needles: 2.75mm and 2mm (ouch)
