Getting My Consew To Give Me A Pretty Stitch

[kayrunp]

The stitching on my consew is a bit jumpy and looks a bit like a long line. My lower bobbin tension is as tight as it gets.

I am also wondering if I need a longer stitch for heavy canvas and leather?

If that straight line is on the bottom of your fabric, you need to loosen your bobbin tension. Your bobbin tension should not be maxed out. If it is, then you have no adjustment for your top tension. If when you pull the bobbin tension and it's really tight, loosen it up and readjust the top to balance the stitch.

As for the "wandering" in the fabric, you're going to get that with heavy woven fabric such as canvas. The needle is actually jumping back and forth between your warp or weft threads. You can try a larger needle and larger thread. For canvas, 5 stitches per inch looks decent. Same for leather. Generally, the lighter the material, the shorter the stitch length. For denim jeans, we use 8 spi as a starting point.
