Such a comfortable sweater or vest. The softness of alpaca without the heavy weight can be found in Snuggle, a blend of Alpaca, wool and acrylic. The pattern has an open front but buttons and buttonholes could be added easily enough.

Size 38 (42, 48, 52, 58)“

Yarn for Vest 5 (6, 7, 8, 9) balls

Yarn for Cardigan 8 (9, 11, 12, 13)

Either style can add a hood with one additional ball

Another option would be to hold a DK weight yarn such as Classic Alpaca double. In that case, you would need to double the number of balls of yarn to complete the project.
