As part of our complimentary thread selection service, we calculate amount of thread you need and include instructions indicating recommended proper thread usage and where to use the thread. We also include a photo of the canvas indicating thread placement as an additional resource. NeedleWorks offers a wide variety of threads to complement every canvas and every stitcher's taste. Please let us know in the "Notes" section of your canvas order which threads you prefer and which threads we should avoid. If you have additional questions or concerns, please contact us and we will be happy to help.
