I recently obtained a gently used, older embroidery machine. It is a White 3300. I am using it with Embird software to make my own designs. But I keep running into an issue, and I'm not sure what the cause of it is.
Whenever getting to the part of the embroidery that is the outline or outer region of the design I frequently end up seeing my lower thread coming through to the top fabric. But it only happens on the outline of the design. It happened once and I concluded that my fabric was not hooped tightly enough because I had just finished the exact same design and it turned out fine.
But, I just finished a custom design and despite what I try, it happens over and over again on the outline. It happens mainly only on the top and bottom portion of the outline. The outline I created using a column because the outline feature in Embrid did not end up being thick enough (or I didn't know how to make it any bolder). But I am also noticing the lower thread pulling through in the early outline stitches on some text, which are just simple straight stitches. Usually I only notice it when using darker threads. The text isn't a big deal though, because it is quickly covered by larger thicker satin stitches.
Anyways, I've tried adjusting the thread tension, the fabric tension... but I'm afraid if I pull the fabric any tighter it is going to pucker awfully. I do not know if I am just not hooping my material properly or what.
Any help would be much appreciated. Here is an example of the issue on my latest custom design.
I used the same technique for inner brown stitch work as I did for the outer brown stitch work, but only see problems on the outer portion.
