Items needed to pursue a Needlepoint project are permitted in your carry-on baggage or checked baggage with the exception of circular thread cutters or any cutter with a blade contained inside which cannot go through the checkpoint and must go in your checked baggage.
They will for certain let you bring plastic crochet hooks.
Some airports will let you bring metal but another may take them from you - best buy a cheap pair of plastic ones.
I have carried yarn & crochet hooks in and out of the country many times. Was horrified this week when an airport security officer in Santiago, Chile, grabbed my three blunt-ended crochet hooks, proclaimed "Weapons!" and threw them in the trash can with a flourish. They were with yarn & I am 67 years old & don't look dangerous. I was so surprised I forgot to remove my favorite stitch-counter from one of them. Then he gleefully seized my too-large tube of really good sunscreen, which I had forgotten to put in my checked bag, cried "Three ounces!" and threw that in the trash, too. So beware.
Probably so (unless you intend to you take a few hundred, pass them out to all passengers on board and convert them all to blunt-instrument wielding fanatics). But I would check ahead with the airline. And ask where you can get one of the cheap needles at the destination. But I really doubt they are worried too much about people passing the time crocheting during a transPacific or trans-Asia flight.
There are some airlines that will not allow crochet hooks or craft needles and yarn on their flights. Why not telephone the airline and check?
Nope, it is considered a weapon.
Can I carry a picture frame aboard with me its made out of metal
Well you can not take your crochet book and yarn with you on the airplane so it is not allowed by the airline management to take the crochet and yarn on the plane. As you have seen that from the last few years back due to the American attacks the airline and travel agencies strengthen the level of security. So you are not allowed for carrying the any thing which is made up of the metal. The crochet is made up of the metals so you cannot take it with you on the plane as this is against the law and regulations.
If you try to take these things with you on the plane you will get caught by the scanners as they can scan all the metal things so you can not take these things with you on the plane because it can subject with the different risks and security reasons for you. So this is why you cannot take the crochet and plane with you even in your luggage. Most of the crochets are made up of the steel and with a needle so you can not take this with you on the plane.
