I have made mine a bit vintage with ash rose and olive green silky fabric and some lace trims. You only need small amount of fabrics and trims. You could also use some vintage trims from your family or add a detail from your parent's or grandparent's weddings.
Step 1: Things you will need
*some kind of fabric for the roses-30cm and leaves and bottom part - 25cm
*a styrolit cone, mine was about 20 cm high
*lace and trimmings for decoration (I didn't use everything on the photo)
*fusible interfacing (something that will stiffen the fabric if you're using thinner fabric like I did)
*sewing machine (you could do this by hand though)
*some kind of glue, I used a glue gun (make sure to use a glue that doesn't dissolve the styrolit)
*scissors, needle, thread
Step 2: Start making a rose
Take one of the pieces and fold long sides together, wrong sides facing. If you want to make it easier for yourself (that I dodn't in the beginning) do this:
Adjust your sewing machine to a long stitch and a loose tension. This will make your fabric crincle while you sew which is exactly what we want here.
Start coiling the fabric from one end shaping a rose. Sew little stitches by hand to keep it from unrolling, sewing through all layers as you go.
