Crocheting tissue bags
I found this instruction for crocheting tissue bags on youtube. (You may search for an English one with "crocheting tissue bags").
At first I just found them cute and since one may finish them very fast, I just tried it. Meanwhile I managed to crochet four pieces and I am also using them once in a while. I find it practically having them in the pocket of my jacket or on my desk. I also think they're a neat gift.
