I've never had holes in my toes. What I started doing was just using KFB for increases on toes. It looks great and you never notice it. You just have to work it so you do the increase on one side one stitch in so they end up in the same place.
Here's what I do which is a rounded wedge toe using magic loop for MY
Using turkish toe cast on I cast on 16 (which puts 8 stitches on each needle)
1. Increase row- *(KFB, knit until 2 stitches remain on needle KFB, K1) repeat from * on other needle
- Repeat increase row every row until 18 stitches
are on each needle
- Knit 1 row plain, followed by increase row. Repeat until 24 stitches are on each needle
- Knit 2 rows plain, followed by an increase row. Repeat until you reach your ultimate stitch count
My ultimate stitch count was 28 stitches on each needle or 56 total. If you need more then repeat the final rows till you reach it.
I got this from my pattern and I chose the rounded wedge because I have Flinstone feet.
You get the idea though about increases if using KFB.
