The coat I'm making for DD, BWOF 09-2009-146, has slashed pockets with welts, and I realized I've never done this exact style before so I took some pictures during construction. It's not much different than other welts I've done, but maybe the pictures can be helpful, especially to someone who runs away like Speedy Gonzales from anything that says slash!
My advise to newbies in regards to welts:
*Take your time to prepare.
*Cut everything with exact seam allowance.
*Mark all seam lines and start/stop points.
*Baste pieces together by hand along the exact lines before machine stitching
*Cut to the exact points- no more, no less
-it is helpful to use a magnifier for the last one:))
If you do this, the welts will be successful. It is so worth taking this extra time to prepare. The reward- besides fab pockets- is that you will embrace welts and include them whenever you can. And those 3 - 4 dots BWOF patterns? All yours, baby :))
