If signature materials need to be used, the background color of the signature materials should be white (in order to better blend with the color on the back of the card). Try to leave a space of about 4mm on the top, bottom, left and right sides of the back of the card, so as not to cut off the words or patterns on your side when cutting.
You can go to Weibo to search for a signature, or you can search for this person's name and signature on Baidu. And small card materials. You can also find some selfies or small card scans in supermarkets or personal bars in Weibo, and Baidu will also upload some small card scans (the scans found in Baidu or Chaohua cannot be used for commercial purposes unless the publisher agrees).
As long as you enter the corresponding keywords, such as "small card", in the search box on the homepage of the design draft, the website will automatically filter out the matching material templates. The material template in sketch design supports online editing and creation. Just click on the template you like to enter the online editing page. Downloading and saving works can be downloaded and saved directly as long as the operation is completed, and users can choose different file saving types.
You can use color cards. Authors can write sentences on the front, comments, introductions and valuable excerpts on the back, and older ones can be more detailed. The title, author and background of the work are on the front, and comments on meaningful and valuable excerpts of the work are on the back.
