I am very new to crochet, this is my first project and I need some help!
This is what the pattern says:
2. Do 1 double crochet, 1 chain, 1 double crochet and so on until the end of all the previous chains, creating a net.
3. Turn and go on to crochet a net, make 1 at right for 4 times.
4. Then, always on the right side, decrease 1 tr over 2 sts, creating the earsí holes.
I think I understand it, but how do I "make 1" and how do I "decrease 1 tr over 2 sts"? What does "tr" stand for?
