Dear fellow knitters,
Help came through in the late night hours when I needed it with a complicated shawl pattern. Can anybody offer up a simple men's sweater vest pattern for dk yarn? (acrylic/cotton/linen blend). Will keep searching... have had the yarn for about 20 years and need to at long last come through for my loyal hubby. Smiles and thanks!

This has all basic patterns,
Plain v neck vest (here called 'Mens Spencer') might suit.

Here are three patterns you might want to take a peek at:

Two button up "unisex" vest patterns from lion brand:
