simon, I also am a fan of Lavender & Lace. I am now working on Celtic Spring for our grand daughter. There are portions of the design where I need to either apply stitches or beads off the main body of work. One of the things I love about this chat room is that I stumbled across a conversation a while back discussing how to anchor stitches that are away from the main body of some of the designs L&L produces. These nice folks put me on to something that I think would help you!!
Google: Scarlet Quince.com....
On their home page, click on solutions
You will see: Top questions - scroll down - Under cross stitch patterns & stitching - select #12 Tutorials.
Scroll down on the left side in red lettering - access "anchoring" - then select "Pin Head Stitching on linen or even weave". It will give you a process to anchor a stitch that is "out there by itself"! I have tried this and it works perfectly. They give you step by step pictures of how this is done. I hope this helps you....it sure did me!! Have a great fourth!
P.S. I just enlarged the picture you submitted.....it is just beautiful. I love the color you are placing the Angel on. Your stitching is perfect!!!! Carol
