So glad you have made a start and it doesn't matter if you're not using the suggested colours so long as you like your own choices. You'll soon get used to stitching on the linen - I love working with linen as it's so much softer than aida. I am sure you will have this finished before too long. Linda x
The most crucial thing is that You like the colors. I often use what I have on hand. Linen gets easier as your go. I do use a magnifier. Looking forward to seeing your WIPS.
