How big is the booth? Black & white is good but to add "POP' have another color as accent such as lemon yellow antique roses to place around. Does it have shelves? If everything is flat on a wall you need some cutouts with some color such as sm.Victorian. Maybe cut pics of covers of magazines from thrift shop. Hot cars, saiboat in bay,Paris St. etc. but something to break up the bk/wh look. People have to envision the frames in their homes. Having pics in some will help but are they all bl/wh photos? Say a wall 5 ft tall 8 ft long would need about 5 -7 bits of color. Attach cutouts. Would be better to have some shelves as some folks do not have much wall space so few pics could grace a shelf or small table with cloth that is very "in" color. A lamp in keeping with style you choose puts light on pics & is nice if allowed. Tablecloth can be fabric sq. that is folded under at bottom & pinned on in back so looks like a draped cloth. GF & I had booth 5 ft high x 8 ft wide & 8 ft deep. You have to "grab" people's attention so need a little bling. We were selling antiques & her handmade things. We did quite well but then they sold the building. If you have couple of shelves (could be store bought) add cloth, doily, small vase with high quality silk flower ,something that spells home, on another wall maybe more formal look,small book, couple of keys with decorative look. Look at magazines, other booths etc. Just frames on flat walls won't get you the sales that you'll get if the booth has personality & don't forget the floor, is it tile, carpet etc. It needs to look good with the rest. After all this is done you must keep everything clean & sparkling, dust & blurry glass in frames says things arn't going well or sloppy space sloppy work on frames. You want your booth to be a "knockout" Don't know what area of country you are in but if most folks are into country add country touches, European look ,pipe on book etc. Check out your competition & see what the other booths have & write down what & how many of each type booth & make your's different. I would use the letter ones on back wall as when folks look in they would see the letters straight on & would be good selling point. If walls are a mess cover them with fabric or repaint if allowed don't go dark on that as would make booth seem tiny. Lots to think of but study booths you like & note what they did. Incorperate some of that in your's. Good Luck! Jan
