You can expect congregations to not focus so much on designs or interiors as it is not the top priority. Then again, more congregations are thinking of fusing function with style just because it is possible to do so. With a theme for guidance or a celebration to look forward to, surely this project will be a fulfilling one.
You can interpret your choice of design in many ways. Take for instance the verses that are commonly shared by believers as it best represents this joint interest. On the other hand, there are photos alongside symbols that could be interpreted artistically so that they will look good on banners.
As for the size, be careful not to over estimate because this could block out a significant portion of the space. A great way to start is to decide where you want to place the flag or banner so that you can easily determine what estimates to make with your measurements. Properly measuring the space in all aspects is a necessity if you want it to perfectly blend with everything else.
Patterns should also be planned as well if you want to be as creative as you want. A seamstress can help you out on this as they are experienced in handling this kind of task. Also, ask for advises along the way so that you can be guided with properly achieving the look that you want.
There is a variety of fabrics that serve different preferences for style alongside appeal. You can be as minimal or as experimental with the patterns based on how it fits the space or if it already is accepted by everyone. Just remember that the overall design should be fitting for the area of the congregation while representing your beliefs.
Making a prototype is another essential step especially if you want to encourage everyone to be part of the process. Once someone can demonstrate to them how the steps should go about, they can follow suit as well. From this collective effort, you can tell that the work will be accomplished in no time while giving everyone a sense of joint fulfillment.
When you have a great material to begin with, then the process would be easier for you to manage. That is, if you are fond of going DIY to ditch the commercially made products in the market. True enough, it is a good exercise for your creativity as well as team work, so let this serve as an activity that will strengthen your bond with the youth.
If you want something new for a change, then go for wall hangings for added fun. Your interiors could use a little face lift if it has been looking bare for quite a long time already. With Christian banners and flags, you can make sure that even through the design process, you can still honor your beliefs into a creative form.
