Some of the tools I used during the design process,and the one I used most was actually an A4 sized laptop,this grid book,and I would carry a stationery bag with me,although we would have cell phones now,there will be tablets and other electronic devices that are more convenient to record,but I'm used to writing them down on paper in the first place,although it may take a while,and I have to carry them to my computer,but I think this record is worth the time,in the application of the software is not really special,I use the same software with everyone,in inspiration and books,I really like the design of the book,in particular,some design magazines,usually more quickly than design books,can present some good design,or fashion some popular trends,if you want to know them quickly,you can pay attention to some magazines,if you need to study some of the knowledge that has already taken shape and can have a final conclusion over a long period of time,you can read some design books,but I'm not special,i recommend which one to read,because there are so many of these books,and there's really no way to rank them one by one,because really,maybe I found a good one,but there will be a better one,and we don't have to take it seriously in this regard,once you've seen it,you'll absorb the knowledge,and that's good.
