If you don't like your T-Shirt anymore and it is still in a good shape, it is perfect for baby sweater:
A friend of mine told me to use fabrics with stripes or other patterns as the little ones love to use clothes as a napkin ;-) and so you wouldn't see it strongly if you don't have the chance to change the clothes. So I will consider this in my next project.
Fitting to the sweater above (the beige one) I made pants using brown baby-cord.
Mmmh, hope someone is reading my stuff ;-). However, I love to write it ;-).
