Very well done, your blog post! Really beautiful in the whole composition. The choice of your images, the photography itself, the subject (leggings), the little words between the photos, the remnants of the cut fabrics and the threads, everything rhymes with the whole. Your question at the beginning, engaging your reader right away, you made this blogpost with a lot of attention to detail and aesthetic, just like the actual sewing work.

To answer your question, as a child I admired this skill so much and to me tailors were demigods, haha! :D My sister and mother gave me a sewing machine a good 25 years ago, I had taken a course then but dropped it. I started again about five years ago and haven't been able to stop since.

Just like you, I've always loved going to flea markets to buy my clothes and now I can change the things I like in terms of fabric but where the cut doesn't fit. I often buy extra large things, unravel the seams and then make something new out of them. I made a 20s dress out of my husband's trousers and an old skirt, it was a lot of piecing together, but that's what I found challenging.
Here you can see the result. In the meantime I have made a few changes to the dress.

How wonderful, I will continue to follow your blog! :) Greetings from Germany!
