Depending on your particular project you'll want to take the following items under consideration as you select your thread for your heirloom quilt.
- What Color is usually a question asked by quilters and the answer is ---it depends. For the piecing a color matching the darker blocks maybe what you need. For quilting, if the quilting is the part of the project that you want to pop then use a contrasting thread. For beginning quilters a matching thread that blends stitches into the background may be called for. Whatever color you select do a sample before you apply to your entire quilt to make sure you are getting the affect that you want to achieve.
- Quilting and Piecing Thread or is All Purpose all right to use? Quilting and Piecing Thread is specifically designed to be used in quilting. Using a fine piecing thread can help keep your piecing seam accurate---the finer the thread the easier you'll find it to keep accurate. A cotton thread of size 50 is recommended by expert Debra Wagner in her book Teach Yourself Machine Piecing & Quilting.
