Inspiration...Knit Boucle Vest

Here's a lovely knee-length vest:

This would definitely be a fun extra in the wardrobe.  This is the Soft Boucle Knit Vest w/Patch Pockets & Chain Trim from St Johns Collection.  Price tag:  $1495.00.  To check it out closer go to Neiman Marcus.  This is a knee length vest with patch pockets and trim.  Note that the trim looks like the selvage so you would want to make sure that the desired fabric had a nice selvage.

As far as the pattern goes, any unlined jacket pattern with the correct features should be good.  It would be even better if it was already fitted.  If that doesn't sound good, this pattern would work:

The lapel is missing but you would still end up with a nice sweater vest.  This is the Sweater Coat by Loes Hinse Design.  One of the views has patch pockets. 

Here's one more:

 This is McCall's 7476.  This pattern gives the vest with a slightly different silhouette with the shawl collar and dropped shoulders but it would still be good.

Hope your inspired to make something beautiful.

Happy Sewing!
