Hi there and welcome from Texas! Yes, Tartan and Thimblebug got you covered.
I don't think any of the applique patterns I've ever used had seam allowances included - you have to add them in the cutting. I usually add 1/8" - 1/4" all around for starch-prepared pieces, depending on the size of the piece and complexity of the design. Simple circles, for instance - 1/8" is fine.
For needleturn, I pretty much use 1/4" and trim as necessary for points.
Lots of more experienced applique-ers here, so don't hesitate to ask questions when you want to - or show off your work with pictures! We love pictures!
