i believe a general opinion about using bias tape for binding is that it mght mot be color fast and it is usually made of a less quality than the fabric used in the quilt. I find it a bit awkward (if that is the word) to use as it already has the folds in the tape. I am not sure you would find it will take less time to use packaged bias tape and it certainly is more expensive. Now why do you need the bias. Only about 4 yds to the package and the ime you would take in pressing out some edges and working more carefully because it is on the bias, you can spend cutting your own.
Do you really need the bias?
